Bathroom Remodeling in Bryn Mawr, PA

Bryn Mawr bathroom costs — why Main Line primary baths run higher

Bids for a project like this land all over the map — and the lowest one is usually the one that climbs the most once the walls come down. We’d rather hand you the honest range up front.

Tier	Range	Typical Bryn Mawr project
Bath Refresh	$25,000 – $40,000	Refresh on a post-2000 secondary bath
Full Bath Remodel	$35,000 – $65,000	Stone colonial hall bath with tub-to-shower conversion
Primary / Master Bath	$50,000 – $90,000+	Stone colonial primary suite with full replumbing and footprint expansion

Two dials set the price: scope and finish — and they move independently. Scope is how much work and how big the project is — a bath refresh updates surfaces and fixtures in place; a full bath remodel rebuilds within the room, often converting a tub to a walk-in shower; a primary suite is the biggest by nature, expanding the footprint and replumbing. Some of that is locked in — a primary bath is always the largest room — but finish is the separate dial: a refresh can still get Brizo or Waterworks fixtures, while a full primary suite can stay measured with Delta fixtures and a Tribeca vanity. Every shower, at any tier, is built on a fully-bonded Schluter KERDI, Wedi, or RedGard system. We’ll install whatever you spec — the brands below are simply the lines we reach for most.

Bryn Mawr stone colonial bathrooms typically land in the upper end of the published ranges because of the replumbing, subfloor work, and structural realities of expanding the footprint into adjacent space. The Primary Bath tier doesn’t carry a hard ceiling — fully custom primary suites with millwork integration, premium fixtures, and footprint expansion regularly exceed $90K. A primary bath remodel in a 1925 Bryn Mawr stone colonial involves real structural and plumbing work that a 2010 Newtown Square contemporary bathroom doesn’t.

Aging-in-place additions are increasingly common in Bryn Mawr primary baths — curbless showers, grab bars (designed to look like towel bars, integrated into the design), comfort-height fixtures, wider doorways. Adds $3K–$8K at any tier.

Frequently Asked Questions

How much does a bathroom remodel cost in Bryn Mawr?

Bryn Mawr bathroom remodels run $25,000 to $90,000+ depending on scope. A refresh on a post-2000 secondary bath starts around $25K–$40K; a stone colonial hall bath with a tub-to-shower conversion runs $35K–$65K; a stone colonial primary suite with full replumbing and footprint expansion runs $50K–$90K+, and fully custom suites go beyond that. Bryn Mawr projects tend to land at the upper end of each tier because the replumbing, subfloor work, and structural realities of expanding a pre-1930 stone colonial add real cost. The free cost guide above breaks every tier down line by line.

How long does a Bryn Mawr stone colonial primary bath remodel take?

Most Bryn Mawr primary-bath remodels run 5–7 weeks of active construction once tile and fixtures are on site. The full timeline from first call to final walkthrough is typically 2.5–4 months, because a pre-1930 stone colonial adds steps a newer home doesn’t — selective demo around plaster, full second-floor replumb, subfloor leveling, plaster ceiling restoration in the room below, and Lower Merion Township inspections between phases. We give you a hard date at proposal and update it weekly in the JobTread portal so you’re never guessing where the project stands.

What’s included in your fixed-price quote?

Everything we can see at signing: design, all materials (tile, vanity, fixtures, hardware), all labor and trade partners (plumbing through our plumber, electrical through our electrician, tile, finish carpentry), permits, inspections, dumpster, project management, and the final walkthrough. The known old-house work — full second-floor replumb, subfloor reinforcement, plaster ceiling restoration below — is priced in, not left as an allowance that balloons mid-project. The only thing that changes the number is scope you choose to add after signing, documented and approved by you in writing first.

What happens behind a 1920s Bryn Mawr stone colonial wall?

In a pre-1930 Bryn Mawr stone colonial we almost always find something — corroded cast-iron waste lines, galvanized supply, knob-and-tube wiring, an out-of-level or under-built subfloor, or old water damage under the tub. None of it surprises us; it’s why these projects take real expertise to run. We document whatever we find, photograph it, price the fix, and get your written approval before proceeding. No silent change orders.

Can you expand my primary bath into an adjacent closet or bedroom?

Yes — it’s one of the most common Bryn Mawr primary-bath asks. Original stone colonial primary baths run 50–75 sq ft, which won’t fit a double vanity, walk-in shower, and freestanding tub. Absorbing an adjacent closet, smaller bedroom, or hall section is usually feasible; we bring in a Pennsylvania-registered structural engineer when a load path is involved. Adding 30–80 sq ft typically adds $15K–$35K depending on whether we’re moving a load-bearing wall and relocating plumbing.

Should I keep the old tub, or convert to a walk-in shower?

Honestly, most Bryn Mawr homeowners convert. The jetted tubs installed in 80s and 90s renovations rarely get used, the motors fail, and they eat space a frameless walk-in shower would use far better. If you genuinely take baths, we’ll design in a freestanding soaker instead — better than a jetted tub and much easier to clean, and it suits a stone colonial primary suite. If you don’t, converting almost always improves daily use and resale. We give you our honest read for your specific room, not a default upsell.

Do you have to replace the cast-iron drains?

Sometimes. We don’t replace them as a default — well-maintained cast iron can last another 50 years. We replace them when the home shows signs of corrosion (slow drains, recurring blockages at fitting joints, visible pitting from the basement) or when the new bathroom layout requires drain runs the existing system can’t accommodate. If we’re already opening the floor and the dining-room ceiling below, replacing while access is open is far cheaper than coming back later. On a typical primary-bath replumb, budget $3K–$6K. We scope and price it before signing — never as a surprise change order.

My second-floor bath is directly above the dining room. What does the project mean for the ceiling below?

Plan for plaster ceiling work. Almost any meaningful bath remodel on a pre-1930 Bryn Mawr home requires opening the ceiling below to access plumbing. We restore the plaster ceiling as part of the project scope rather than treating it as a surprise — and where it’s historic or has decorative plaster, we restore it properly rather than just drywalling over it. It adds 2–4 weeks to the timeline, and we tell you up front which approach your specific room calls for and what it costs.

Can you do aging-in-place modifications without it looking institutional?

Yes — and that’s the case for doing it during the remodel instead of bolting it on later. A curbless walk-in shower, blocking in the walls for grab bars (designed to look like towel bars), a comfort-height toilet, and a bench detail all integrate cleanly when planned from the start. Built in at the framing stage it adds roughly $3K–$8K, and done right you’d never read it as “aging-in-place” — it just looks like a well-designed bathroom that happens to work at any age.

What does Lower Merion Township permitting cost for a Bryn Mawr bath project?

Permit fees through Lower Merion Township typically run 1–2% of contract value. On a $90,000 primary bath, expect roughly $900–$1,800. We pull every required permit, schedule the inspections around the production schedule, and show the permit cost as a transparent line item on the proposal — it’s never buried in markup or sprung on you mid-project.

Do I need to hire my own designer?

No separate designer needed — we’re design-build, so the team that designs your Bryn Mawr bath is the team that builds it; nothing gets drawn that we can’t build for the price quoted (and we work as the build partner regularly if you already have an architect).

How will you communicate with me during construction?

During construction you get one point of contact (Alex or your project manager) who answers calls and texts, weekly progress updates, and a heads-up before anything becomes a problem, plus the live JobTread portal showing schedule, budget, and invoices. On a 100-year-old stone colonial, that communication is the difference between a manageable project and a stressful one.
