If your bathroom is out of date, cramped or showing water damage, the first question is almost always the same: how much will it cost? The honest answer is that the bathroom remodel cost depends on the size of the room and how far you take the project. This guide gives typical price ranges for bathroom remodels in the Bucks and Montgomery County area, explains what moves the price up or down, and shows you how to compare estimates fairly.
The short answer
Public 2026 cost guides for Pennsylvania generally put a full midrange bathroom remodel at roughly $15,000 to $30,000. Smaller bathrooms with a lighter scope often land between $8,000 and $18,000, and large primary bathrooms with custom showers and layout changes can reach $35,000 to $55,000 or more. Nationally, cost guides put the average bathroom remodel at about $16,500 in 2026. These are general market ranges, not a quote. The only way to know your number is a written estimate based on your bathroom.
Bathroom remodel cost by project scope
Most projects fall into one of three buckets:
- Small bathroom refresh ($8,000 to $18,000). A hall or guest bath of roughly 40 square feet: new vanity, toilet, tub or shower surround, flooring, lighting and paint, with the plumbing staying where it is.
- Full midrange remodel ($15,000 to $30,000). New tub or tile shower, new vanity and fixtures, tile flooring, lighting, ventilation, and fresh drywall and paint throughout the room.
- Primary bathroom remodel ($35,000 to $55,000 and up). A larger space with a custom walk-in shower, double vanity, upgraded plumbing and electrical, heated floors or a changed layout.
Many older homes in Doylestown, Collegeville and Norristown have one small original hall bath plus a larger primary bath, and the two often carry very different price tags for that reason alone.
What changes the price
- Room size and scope. More square footage means more tile, flooring and labor, and a full gut costs more than a surface update.
- Plumbing moves. Keeping the toilet, sink and shower where they are is the single biggest money-saver. Moving a drain or adding a fixture can add roughly $2,500 to $5,000 per move, according to public cost guides.
- The shower. A custom tile walk-in shower costs more than a prefabricated surround, and it is usually the largest single feature in the budget after labor.
- Materials. Tile, vanities and fixtures range from builder-grade to luxury, and the spread between them is wide.
- What is behind the walls. Older homes in Bucks, Montgomery and Chester Counties sometimes hide galvanized supply lines, dated wiring or water damage once the demo starts. A good estimate explains how surprises like these are priced before you sign.
- Ventilation and waterproofing. A properly sized exhaust fan and a correctly waterproofed shower protect the room for years, and they belong in the scope.
- Permits. Most townships require permits for plumbing and electrical work, and fees vary.
Keep the layout, save the money
If the current layout works, leaving the plumbing where it is keeps a remodel in the midrange tier instead of the upscale one. You can still transform the room with a new shower, new tile, a modern vanity and better lighting. If the layout genuinely fights you — a door that swings the wrong way, a vanity nobody can stand at — get a written price for both versions and compare them. The difference is usually the plumbing move, and seeing it on paper makes the decision easy.
Why the lowest bid is not always the lowest cost
Two bathroom estimates can differ by thousands of dollars and still look similar on the first page. Before you compare prices, check that each one lists the same things:
- Tub or shower: prefabricated surround or custom tile, and which brand
- Vanity, countertop, sink and faucet models or clearly stated allowances
- Tile material and square footage, and who supplies it
- Waterproofing method behind the shower walls
- Plumbing and electrical scope, and whether any fixtures move
- What happens if hidden damage is found, and the pricing for it
- Permits, disposal, dust protection and daily cleanup
- Workmanship warranty, in writing
- Proof of license and insurance
Questions to ask before you sign
- Are you licensed and insured in Pennsylvania? Can I see the proof?
- Is the estimate in writing and itemized?
- Will your own crew do the work, or which trades do you subcontract?
- How do you waterproof the shower, and what warranty covers it?
- How do you handle surprises found behind the walls?
- What is the timeline and the payment schedule?
