Three Bathroom Estimates Where the Homeowner Bought the Tile, and What That Did to the Price
"Do contractors supply materials, or should I buy my own?" is one of the most common questions people type when they start pricing a bathroom. Its sharper cousin is "my contractor wants me to buy the materials. Is that normal?" Both deserve a better answer than "it depends," so here are three bathroom estimates we wrote in 2026 where the homeowner bought some or all of the materials: the price, what each covered, and what it deliberately left out.
Names and street addresses are left off. The scopes and prices are taken from the estimates themselves.
Estimate 1: a hall bath in northeast Pasadena, $14,980
This was the closest of the three to a full remodel. The scope, written in July for a home in the 91104 ZIP code: demolish the wall and floor tile, shower door, toilet, vanity, baseboard and ceiling fan, and haul it all away; hang cement board on the shower walls; frame new niches; set new wall and floor tile; reglaze the existing tub rather than replace it; install the new toilet, vanity, fan and mirror; patch and paint the walls and ceiling; and run new painted baseboard.
The $14,980 covered all labor plus the rough construction materials. The homeowner bought the finish materials, which the estimate names one by one: tile, shower door, toilet, vanity, sink, faucets, cabinet, ceiling fan and mirror.
Estimate 2: two baths and a closet in Arcadia, $9,860
Written in early November. In the main bath: tear out the tub, shower doors, a foot of perimeter tile, the vanity, toilet and mirror; supply and install a walk-in shower pan; tile a two-foot surround; patch and paint. In the second bath: strip the wallpaper, then patch, texture, prime and paint, and install the owner's new vanity and mirror. In the closet: pull the shelving, patch and paint.
Here we supplied the shower pan. The homeowner supplied the tile, toilet, vanities, sinks, faucets and mirrors.
Estimate 3: a tub-to-shower conversion in Alhambra, $6,980 labor only
Remove the tub and build a tiled shower over a hot-mopped pan, the tar-and-felt method that is still common in Southern California, with a bench, a recessed niche and a sliding door. Also: remove the old countertop and install a new sink, a medicine cabinet, a mirror and a grab bar, replace six broken floor tiles, and swap the toilet. This one was labor only. The homeowner paid for every material directly, down to the setting materials.
What these prices do and do not tell you
None of these is the full-remodel number from our post on whether $10,000 is enough for a bathroom remodel, where we put a same-layout remodel at roughly $20,000 and up. The gap is mostly what is missing from the invoice. Estimate 1 came in under $15,000 because the tile, fixtures, vanity, fan and glass were on the homeowner's credit card instead of ours, and because the tub was reglazed instead of replaced. Add what the homeowner spent at the tile store and the plumbing showroom, and the project lands in the range our Pasadena bathroom remodeling page publishes.
So buying your own materials does not make a remodel cheap. It moves part of the cost off the contractor's invoice and onto yours, and some of the risk moves with it. All three estimates also carry the same two lines in the fine print: the price is good for 10 days, and it does not include labor or materials needed for problems found after the walls are open. That is true whoever buys the tile.
What you actually save
You save whatever margin the contractor would have added to those items, and you get to shop sales, use a designer's trade discount, or choose a vanity no contractor would stock. Markups vary by company, so do not guess: ask for the materials line broken out, and compare it with what you would pay for the same model numbers.
You also take on a job you may not have priced: you become the purchasing department. That means choosing, ordering, tracking deliveries, opening boxes and handling returns, on the contractor's schedule rather than yours.
What it costs you, in the places nobody prices
Timing. A backordered vanity stalls the plumber, and a crew waiting on a delivery is a cost someone pays. The logic is the same as in our kitchen remodel order of operations: everything you are buying should be on site before demolition starts.
Damage and wrong items. Open every box when it arrives, not on install day. A chipped sink or the wrong faucet finish found by the installer means a return trip.
Quantity. Buy extra tile for cuts and breakage, and keep a box after the job. Estimate 3 shows why: those six broken floor tiles could only be replaced because the owner still had matching tile. If you choose a shower wall material other than tile, our comparison of tile and panels for Pasadena showers covers the trade-offs.
Compatibility. Shower trim only fits the valve body from the same manufacturer, so settle the brand before the wall is closed. Measure the toilet rough-in, the distance from the wall to the floor drain, before you order; 12 inches is standard, but older houses turn up 10 and 14. And do not buy a frameless shower door off the shelf: the glass is measured after the tile is set.
Code. California's plumbing code requires new toilets and showerheads to meet low-flow limits, so check the label before you buy, and a permitted remodel can require other noncompliant fixtures in the house to be replaced as well, as we explain in our post on why a Pasadena permit can mean new toilets. Bathroom ventilation has its own rules, covered in whether a window can replace the bathroom fan.
Warranty. A contractor's workmanship warranty covers the installation, not a defective product. If an owner-supplied faucet fails, the claim is between you and the manufacturer or the store.
Our recommendation: buy what you see, let the installer buy what is behind the wall
Buy the pieces you choose by looking at them: tile, the vanity and top, the faucets and shower trim once the valve brand is settled, the toilet, the mirror or medicine cabinet, lighting and accessories. Leave everything that can leak or that sits behind finished surfaces with the contractor who installs it: the shower pan and waterproofing, cement board and setting materials, the valve body, drain parts, supply lines and shutoffs, and the fan duct and wiring.
The reason is accountability. If a shower leaks behind new tile in year two, one company should own the whole assembly, materials and installation. Estimate 3 shows that a fully labor-only job can be done, and it was. But given the choice, we would rather supply the pan and waterproofing ourselves, and we will say so when we write the estimate.
How to ask for an owner-supplied estimate
Ask for the excluded items to be listed by name, the way these three estimates list them, so nobody argues later about who was buying the towel bars. Ask exactly what "rough materials" includes. Agree on a delivery deadline for everything you are buying. The written contract should describe the materials as well as the work; the CSLB explains what California requires in its guide to home improvement contracts, and our remodeling contract checklist walks through the rest. Check any contractor's license with the CSLB license lookup, and if the work touches plumbing, electrical or ventilation, ask who will pull the permit through the City of Pasadena Permit Center.
The same question comes up on a kitchen remodel, an ADU build and even a custom deck, and the same split answers it: buy what you will look at, and let the installer own what holds water or holds weight. Finished bathrooms and kitchens are in our project gallery, and more answers on cost and scope are in the remodeling FAQ.
