From cosmetic refreshes to full custom gut renovations, TrioTimber designs, permits, and builds bathrooms across Greater Los Angeles and Orange County — with transparent tiered pricing, a dedicated project manager, and a 1-Year Workmanship Warranty on everything we touch.
Free consultation. No obligation. Response within one business day.
Bathrooms are small rooms with big risks. Behind the tile is plumbing, ventilation, and waterproofing that — done wrong — leads to leaks, mold, and rot you won't see until it's expensive. The right contractor builds for what's behind the wall, not just the finish on it.
Improper waterproofing and shower pans cause leaks that rot subfloors and grow mold behind walls. We build to code with proper membranes and pass moisture-sensitive inspections.
Old galvanized plumbing, failing ventilation, or water-damaged framing become “change orders.” We inspect and itemize up front so the number you approve is the number you pay.
Moving plumbing or altering layout without a permit can fail inspection, void insurance, and complicate a future sale. As a licensed GC, we pull every required permit.
Rushed tile work, poor grout, and bargain fixtures crack, stain, and leak within a couple of years. Our work is built to last and backed by a 1-Year Workmanship Warranty.
It's the most important question for your budget and your timeline — because it determines whether your project needs city permits and inspections. Here's the honest difference.
Not sure which one you need? That's exactly what our free consultation is for.
As a licensed general contractor (CSLB #1115717), TrioTimber manages the entire permit and inspection
process for you — so a remodel never becomes a code-compliance problem.

We believe in radical transparency. Most contractors hide their numbers — we'll show you ours. Bathroom projects in Greater LA and Orange County generally fall into three investment tiers.
* Baseline estimates based on typical Greater LA & Orange County market data for planning purposes only. Your exact investment is confirmed in a written, itemized proposal after a free on-site evaluation. Final pricing varies by bathroom size, material selections, structural scope, and your city's permit requirements.
A prefabricated (stock) vanity is the most budget-friendly option and comes in standard sizes. A custom, made-to-order vanity is built to your exact space and storage needs — a major swing in a bathroom budget, especially in tight or oddly shaped rooms.
Keeping fixtures where they are keeps costs down. Moving the toilet, shower, or sink — or converting a tub to a curbless walk-in shower — means relocating plumbing and triggers a city plan check and inspections. It transforms the room, but it changes the number.
Tile choice and the amount of tiled area drive both material and labor cost, and proper waterproofing is non-negotiable. Fixtures — from a basic faucet to a thermostatic shower system or soaking tub — span a wide range we help you prioritize.
Older LA & OC homes often hide outdated wiring, galvanized plumbing, poor ventilation, or water damage. We inspect before we quote so these are planned for — not billed later as surprise change orders.
You can always find someone cheaper. What you can't always find is a licensed contractor whose price includes full permit management, a dedicated project manager who answers the phone, proper waterproofing and build-to-inspection quality, and a warranty that means something. A bathroom done wrong leaks — we price it to be done once, and done right.
Drag the slider to see a tired, dated bathroom become a fully waterproofed, spa-grade space — same room, same camera angle.

Tile, stone, waterproofing, and fixtures span a wide range — your dedicated project manager helps you choose the finishes that fit your style and budget at your free consultation.
One licensed team from the first measurement to the final inspection, so nothing falls through the cracks between a designer, a contractor, and the city.
We measure, assess plumbing and what's behind the walls, and talk through your vision — at no cost and with no sales pressure.
A clear, line-item scope and price — so you know exactly what you're investing in before any demo begins.
If your remodel needs a permit, we handle the plan check submission, corrections, and city coordination for you.
A dedicated project manager runs the build to code with proper waterproofing, keeps you updated, and passes every required inspection.
We don't call it done until you're satisfied — and our work is backed for a full year.
We'd rather be honest now than waste your time later. We're not the right builder for every project — and that's on purpose. You may want a different contractor if:
We're not the cheapest quote you'll get, and we won't pretend to be. Our work is custom millwork and full-service remodeling built to last decades, priced accordingly. If you're choosing purely on price, another builder will serve you better.
Our custom kitchen and bathroom remodels start at a $15,000 total investment, and detached ADUs start at $150,000. If your budget is well under that, we'll tell you honestly rather than value-engineer your project into something we're not proud of.
A full remodel runs 8–12 weeks from demolition to final inspection, with design and permitting before that. If your deadline can't move, we may not be able to help without cutting corners we won't cut.
We stand behind our work because we control the whole chain — our people, our millwork, our standards. If you're looking for labor-only or a builder to assemble parts you've sourced, we're not a match.
We're an excellent fit if you value craftsmanship over the cheapest number, you want one accountable team from design through final walkthrough, and you'd rather do it once and do it right. If that's you, book your free consultation.
Answer a few quick questions and a member of our team will reach you within one business day with next steps and a free on-site evaluation.
