Claremont has the oldest intact bathrooms of any city we work in, and the most reason to think before demolishing them. In Old Claremont, the original residential neighborhood a few blocks north of Claremont Village, the houses along Indian Hill Boulevard and the streets around Memorial Park date to the early 1900s, and a good number still have their first-generation fixtures and small-format wall tile in place. Some of that is worth keeping. Most of the plumbing behind it is not, because supply and waste sized for a 1910s house does not serve a modern shower valve, and a century of repairs tends to be layered rather than replaced. The other constraint is administrative. The city asks you to clear Planning and Engineering before a building permit application goes to the Building Division, so there are three desks in the path rather than one. On projects that touch anything visible from the street, the Planning Commission and the Architectural and Preservation Commission may also be involved.
Water here comes from the Golden State Water Company rather than the city, and its Claremont service area also reaches into parts of Pomona and Upland, so the boundary is not where people assume. Roughly sixty percent of the supply is local groundwater and the rest is imported through the Three Valleys Municipal Water District from the Metropolitan Water District. That matters for a remodel mainly at the shutoff and the meter, which is a call to a company rather than a city department. Up in North Claremont the housing changes character again. Padua Hills traces back to 1938 and Claraboya to 1964, both on larger foothill lots against the San Gabriel Mountains, with the access and drainage considerations that come with building on a slope. Wheeler Park and the streets nearer the Claremont Colleges sit somewhere between the two eras.

Tile work in Claremont is the closest thing we do to restoration. In Old Claremont and the blocks near the Claremont Colleges, bathrooms from the early 1900s carry small-format wall tile and hex floors that were laid over mortar beds, and a lot of it is still structurally fine even where it looks tired. The judgment call is whether to repair or replace, and it is genuinely a judgment rather than a default. Repair works when enough matching material can be sourced and the mortar bed underneath is sound. It does not work when the shower valve has been leaking into the wall, which is where most of these jobs actually start. We open a section before quoting so the decision is made with the substrate visible. Where a full replacement is right, we can set tile that suits a Craftsman or Spanish Revival house rather than fighting it.
Vanity replacement in Claremont usually turns into a plumbing conversation in the older housing. A pedestal basin or an original built-in cabinet in an Old Claremont bathroom sits on supply and waste that was never sized or positioned for a modern vanity, and the trap arm height is frequently the thing that decides which units are even possible. We check that at the walkthrough rather than at installation. Because supply here is the Golden State Water Company rather than a city department, a meter or service question goes to them, and we handle that coordination. In the newer North Claremont housing around Padua Hills and Claraboya the job is usually a clean swap, with new shutoffs and supply lines fitted while the cabinet is out. The same is true of most homes near Wheeler Park, where the stock sits between the two eras.

Bathroom flooring in Claremont splits by era as sharply as everything else here. In Old Claremont the floor is often an original hex tile laid on a mortar bed over plank subfloor, which is heavy, frequently still sound, and difficult to tie into modern work at the doorway and around the fixtures. Lifting it is a decision rather than a formality, and where the bed is intact we will tell you if keeping it is the better answer. The same holds through the streets around Memorial Park and Wheeler Park. Up in North Claremont and the foothill lots below the San Gabriel Mountains, the construction is later and the question is simply the condition of the decking around the flange. Either way we lift a section first, check the framing, and price the floor against what is under it.

Ten services, from a single vanity swap to a full remodel that moves fixtures. Tile, vanity and flooring installation are quoted as standalone work, because plenty of bathrooms need one of those and nothing else. The larger remodels are scoped after we see what is behind the wall.
Frequently Asked Questions
Bathroom Remodeling can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
There is no single number, and anyone giving you one before seeing the room is guessing. Cost follows whether fixtures move, whether the supply and waste lines behind the wall get replaced, the size of the tiled area, and what the permit scope turns out to be. A vanity and floor swap in an existing footprint and a remodel that relocates the drain are not comparable jobs. We price after a walkthrough.
Usually whatever forces plumbing to move. Relocating a toilet, a tub drain or a shower valve means opening the floor or the wall, re-running lines, and adding inspections. Tile and fixtures are visible and feel expensive, but they are predictable. The costs that surprise people are the ones behind the surface.
If the work touches plumbing, electrical or structure, yes. Pomona issues building, plumbing, electrical and mechanical permits through Building and Safety at City Hall on Garey Avenue, and the counter runs Monday through Thursday. Swapping a vanity into the same footprint is a different conversation than moving a shower valve. We tell you which category your job falls into at the walkthrough, and we pull the permit.
Schedule follows the permit and inspection sequence, whether fixtures move, and lead times on tile and glass. A single-scope refresh in an existing footprint and a remodel that relocates the drain are not comparable. What we can commit to is a sequence at the walkthrough, so you know which weeks the room is unusable and which are waiting on an inspection.
It depends on what is driving it. Replacing a failing shower pan or a floor that has been getting water under it for years is not really optional, and putting it off makes the eventual job bigger. A cosmetic update is a different decision and worth being honest with yourself about. We will tell you when we think a repair is the better use of your money.
Because more trades work in that one small room than anywhere else in the house. Demolition, plumbing, electrical, waterproofing, tile, glass and finish carpentry all have to happen in sequence, in a space where two people can barely work at once. Add the inspections that plumbing and electrical trigger, and a small room absorbs a lot of labor.

Our house in the Lincoln Park Historic District still had the original hex floor and a cast-iron tub, and every contractor we called wanted to rip all of it out. These were the only ones who asked what we wanted to keep. They matched the tile pattern in the shower and rebuilt the wall behind it properly.

We converted the tub to a walk-in shower in our Phillips Ranch house so my mother could stay with us. The original fiberglass surround came out and they found the subfloor was soft in one corner, which they showed me before doing anything about it. Permit and inspection were handled without me chasing anyone.
Kenneth P.

I asked for a full remodel of the hall bathroom and they talked me out of half of it. The vanity and the floor genuinely needed replacing, the tub did not, and they said so. Quote came in for the work that mattered and the job finished on the schedule they gave us at the walkthrough.
