Complete Bathroom Remodeling Across Cape Cod

Nine towns, from Harwich and Chatham out to Provincetown — and nine sets of local conditions that change how a bathroom has to be built.

On Cape Kitchens has been remodeling bathrooms on Cape Cod for more than 30 years, working out of a design office and showroom at Unit #7, 4250 State Highway in North Eastham, next to Ace Hardware. Owner and designer Vern Hatt is a Massachusetts licensed and insured contractor (Construction Supervisor License #CS62739, Home Improvement Contractor License #177590) and runs every project personally, which means the person who drew your layout is the person who answers the phone when a vanity arrives damaged.

We work in nine communities: Brewster, Chatham, Eastham, Harwich, Orleans, Provincetown, Truro and Wellfleet, plus the wider Cape where a project warrants the drive. Those towns look similar on a map and are not similar to build in. Water supply, wastewater, historic district review, seasonal occupancy, housing age and even delivery logistics change materially between them, and a bathroom designed without accounting for that is a bathroom with a problem waiting in it.

We take on as much or as little as the project calls for: a vanity and top supplied only, a single failing shower rebuilt properly, or a full gut with demolition, plumbing, electrical, waterproofing, tile, fixtures and finish carpentry.

What a Cape Cod Bathroom Remodel Includes

🎨

Custom Design

A layout drawn for the room you actually have — measured on site, not adapted from a showroom plan.

Quality Vanities

JSI vanities on display in our North Eastham showroom, plus U.S. Cabinet Depot and Forevermark in sizes from powder room to double sink.

🗺

Tile & Waterproofing

Floors, walls and shower surrounds set over a proper waterproof assembly — the part nobody sees and everything depends on.

🚰

Plumbing

New supply and waste, valves, toilets, tubs, shower systems and vanity fixtures, with relocation where the layout calls for it.

💡

Lighting & Electrical

GFCI protection, recessed and vanity lighting, and an exhaust fan properly sized and vented to the outside.

🏗

Full Installation

Demolition through finish carpentry, run by a licensed Massachusetts contractor who is on the job site.

Choose your town

Each of our town pages covers the local conditions that actually affect a bathroom project there — the water supply, the wastewater situation, the review process, the housing stock and the practical scheduling. If you know where you are, start there.

Town water or a private well — and why it decides your fixtures

This is the single biggest practical difference between one Cape town and the next, and it changes what we recommend before anything else does.

Brewster, Chatham, Harwich, Orleans and Provincetown are substantially served by public water. Much of Eastham is now connected to a municipal system built out over recent years. Wellfleet and Truro are on private wells almost throughout, and pockets of every town still are.

Outer Cape well water tends to be soft, acidic, and carrying iron and manganese. Low pH corrodes copper supply pipe from the inside, which shows up as blue-green staining and eventually as pinhole leaks inside a finished wall. Iron leaves orange staining on porcelain and grout. Manganese leaves black staining that nearly everyone mistakes for mildew and scrubs at for years.

None of it is fixed by new fixtures. If you are on a well, test the water and get treatment in place before the remodel, and choose non-porous surfaces — quartz rather than marble — where staining would be permanent. If you are on town water, none of this applies and the budget goes into the room instead. We ask which you have at the first visit.

Septic, sewer, and the bedroom rule that catches people out

Most of the Lower and Outer Cape is on private Title V septic systems. The exceptions are growing but still limited: Provincetown has a municipal sewer system, Orleans has built a downtown collection system, and Harwich has been extending sewer through parts of town.

Where Title V applies, here is the nuance that catches people out. Design flow is calculated on the number of bedrooms, not the number of bathrooms. Adding a second full bath to a three-bedroom house does not by itself change your septic calculation. Converting a den, a bonus room, a sleeping loft, a bunk room or a finished basement space into a bedroom as part of the same project does.

Cape houses are full of rooms that have been slept in for decades without ever having been counted, which is exactly the situation where a remodel crosses the line by accident. We check the septic design and the approved bedroom count against your plans before we price the work. A septic upgrade discovered midway through a project is the most expensive surprise in Cape Cod remodeling, and it is entirely avoidable with one conversation at the design stage.

Historic districts on Cape Cod, and what they actually review

Several kinds of review overlay Cape property and they cause far more worry than a bathroom project usually warrants.

  • The Old King's Highway Regional Historic District is the only regional historic district in Massachusetts, running along Route 6A through Sandwich, Barnstable, Yarmouth, Dennis, Brewster and Orleans. Each town has its own committee.
  • Local historic districts exist in several towns, including Provincetown and Wellfleet, administered by town commissions.
  • The Cape Cod National Seashore boundary covers large parts of Eastham, Wellfleet, Truro and Provincetown, with restrictions on improved properties within it.
  • Demolition delay bylaws apply to older structures in a number of towns.

For a bathroom remodel the practical rule is the same across all of them: they review the exterior. Your vanity, tile, shower, fixtures, flooring, lighting and layout are your own business and nobody reviews them.

Where a bathroom project can catch a review is narrow but real: an exhaust fan terminating on a face visible from a public way, a new or resized window, a changed door, a skylight over the shower, or a bump-out to gain floor area. In most cases we design around it — routing a vent to a rear roof plane costs nothing. Where a certificate is genuinely needed it must issue before the building permit, and we build that into the schedule rather than discovering it after demolition.

Ventilation, salt air, and the two things that age a Cape bathroom

More failed bathrooms on Cape Cod come down to moisture than to anything else, and the fan is usually the culprit. We routinely open up bathrooms and find a builder-grade fan that was never adequate, a fan vented into the attic or crawl space rather than outside, or no fan at all in a room with a window nobody opens in February. The consequences are mildew in the grout, paint peeling off the ceiling, a swollen vanity toe kick, and in the worst cases rot in the framing behind the shower.

Doing it properly costs very little at rough-in stage: a fan sized to the actual room volume, ducted in insulated rigid or smooth-wall pipe with as few bends as possible, terminated outside with a damper, and switched on a timer or humidity sensor so it runs long enough after a shower to clear the room.

The second thing is salt air, and it matters most within a mile or so of the water, which on Cape Cod is most of it. Salt-laden air pits chrome plating over zinc alloy, rusts cheap mounting screws, corrodes fan housings and blackens mirror silvering. The answer is specification rather than maintenance: solid brass valve bodies, PVD or living finishes, stainless or brass fasteners, moisture-rated mirrors and sealed fan housings. Those choices cost very little at the order stage and are the difference between a bathroom that still looks new at twelve years and one that looks tired at six.

Showers, waterproofing, and what is under the tile

The single most important part of a bathroom is the part that gets covered up and never looked at again. Tile set over an inadequate substrate is indistinguishable from tile set over a sound waterproof assembly on the day the job finishes, and stays that way for about four years.

A shower that lasts is an assembly rather than a finish: the pan sloped to the drain or a pre-formed tray set in place, a bonded waterproof membrane over cement board rather than tile fixed to greenboard, every seam and inside corner banded, curbs and niches treated as carefully as the open wall, and a setting material chosen for the specific tile. Porcelain, natural stone and mosaic behave differently and cannot be installed the same way.

Curbless and low-threshold showers are now the most requested item across every town we work in, and for good reason — they look better, they are far easier to clean, and they are the difference between a bathroom that works at fifty and one that still works at eighty. On a first floor over a basement or a deep crawl space they are usually straightforward. On a second floor, or over a shallow crawl, or on a slab, it depends on what is underneath. We measure before we promise rather than after.

Vanities, tile and finishes

Cape Cod leans traditional and coastal, and the vanities we specify most often reflect that — painted Shaker and inset doors in white, off-white, soft grey, navy and muted green, furniture-style pieces with legs and a visible floor, and beaded detail where the house calls for it. For the modern houses of the Outer Cape and the renovated condominium units in Provincetown, plain slab fronts and wall-hung vanities are usually the right answer instead.

We keep JSI vanities on display at the North Eastham showroom, and also supply U.S. Cabinet Depot and Forevermark in sizes from a 24-inch powder room piece up to a 72-inch double sink. Quartz is the practical default for vanity tops — non-porous, no sealing, indifferent to the humidity swings in a house closed up part of the year, and far more resistant to well-water staining than any porous stone.

Our Fall 2026 Haven Sage finish has been drawing steady interest across all nine towns. A muted green sits correctly in a house built in 1840 and in one built in 1985, which is a fair summary of Cape Cod's housing stock.

One scheduling detail worth knowing

Cape Cod construction runs on a season, and it is the opposite of the tourist one. The right sequence for almost every bathroom project here is: talk in late summer, design and select through the autumn, order while lead times are short, and build between October and May.

That is when houses are empty, when rental income is not at stake, when trades are available rather than booked three deep, and when a delivery truck can actually reach a house in Provincetown or on 6A in Brewster. A bathroom started in November is finished, cured and cleaned well before the first booking. A bathroom started in April is a race, and races are where corners get cut.

The design and ordering phase is also the part everyone underestimates. Tile in particular can take weeks. Starting the conversation early costs nothing and removes most of the pressure from the build.

A free visit to your home anywhere in our service area, or a sit-down at the North Eastham showroom, to talk through what is failing and what the budget is.

2

Design & Selection

Layout drawings, then vanity, tile, countertop, fixture and hardware selections made from samples you can actually handle.

3

Written Proposal

Detailed scope of work, specified products and suppliers, payment schedule, and our licence and insurance details.

4

Construction

Demolition, framing, plumbing and electrical rough-in, waterproofing, tile, vanity, fixtures and finish work.

5

Completion

Final plumbing and electrical trim, glass installation, walkthrough, punch list and cleanup.

See the Vanities in Person

Vanity finishes photograph nothing like they look in a north-facing Cape bathroom in November, and drawer hardware feels fine in a picture and cheap in your hand. We keep JSI vanities on display at the North Eastham showroom, alongside U.S. Cabinet Depot and Forevermark, plus countertop samples, sinks, faucets and hardware. You can put a door sample against your tile, compare hinge and glide quality between price levels, and see the new Fall 2026 Haven Sage finish in daylight.

Every ADU Needs a Bathroom

Massachusetts now allows accessory dwelling units by right in single-family zoning districts, and interest across the Lower and Outer Cape has been substantial. Every ADU needs a full bathroom as well as a kitchen, and inside 900 square feet that bathroom has to be planned tightly — a compact vanity, a shower rather than a tub, and ventilation and waterproofing done properly the first time, because there is no slack in a small building. On the Cape the first questions are septic capacity and water supply rather than zoning.

Our sister company handles accessory dwelling unit design and construction across the Lower Cape, and we build the kitchens and bathrooms that go inside them.

Cape Cod Bathroom Remodeling Questions

Which Cape Cod towns do you work in?

Brewster, Chatham, Eastham, Harwich, Orleans, Provincetown, Truro and Wellfleet, from a showroom on Route 6 in North Eastham. Each of those towns has its own page covering the local water, wastewater, review and scheduling conditions that affect a bathroom project there. We will consider work further up-Cape depending on the project.

How long does a bathroom remodel take?

A full bathroom gut and rebuild is typically three to five weeks on site once materials are on hand. That sounds long for a small room, but tile and waterproofing have mandatory cure and set times that cannot be compressed, and there are three separate trades that each need to come and go in sequence. A vanity-and-fixture refresh without moving plumbing can be done in about a week. The design and ordering phase ahead of construction usually takes longer than people expect, particularly if tile is being special ordered.

When is the best time to schedule work on the Cape?

Talk in late summer, design and order through the autumn, build between October and May. That is when houses are empty, rental income is not at stake, trades are available, and delivery access is realistic. A project started in November finishes well before the season. One started in April is a race.

Do I need historic district approval for a bathroom remodel?

Not for the interior, anywhere on the Cape. Old King's Highway, the local historic districts in towns like Provincetown and Wellfleet, and the National Seashore restrictions all concern the exterior of the building. Your vanity, tile, shower, fixtures and layout are not reviewed. A visible vent termination, a new or resized window, a skylight or a bump-out can attract review, and where a certificate is needed it must issue before the building permit.

Will adding a bathroom require a septic upgrade?

Usually not by itself. Under Title V, design flow is calculated on the number of bedrooms rather than bathrooms, so a second bath in a three-bedroom house does not change the calculation. Converting a den, loft or basement room into a bedroom as part of the same project does. If you are in Provincetown, or on Orleans downtown sewer, or on a sewered Harwich street, different rules apply. We check before pricing the work.

Do you do powder rooms and small projects, or only full remodels?

Both. A great deal of our work is a powder room refresh, a vanity and top replacement, or a single failing shower rebuilt properly. We are equally happy supplying a vanity for your own contractor to install. Call and describe what you have in mind — the consultation is free either way.
