Siboni Development & Design

Bathroom Remodeling

A bathroom that works the way you actually use it — built to last, finished on schedule.

Overview

Most of the bathrooms we're called about have the same problem: they were built for a different decade and a different household. Tight layouts, tile that never dries out, a vanity that eats the only floor space you have. We fix that — not by ripping out everything for the sake of it, but by rethinking the room around how you start and end your day.

Our crews handle the whole job under one roof: demolition, plumbing, waterproofing, tile, electrical, and the finish work that makes the difference between 'renovated' and 'well built.' You deal with one team and one written scope from the first walk-through to the final walk-out.

Waterproofing done right

Full membrane systems behind the tile, not just backer board. It's the part you never see and the reason the work lasts.

One licensed crew

Plumbing, electrical, tile and carpentry coordinated by the same team — no gaps between trades, no finger-pointing.

Fixed written price

You approve a detailed scope and a number before demolition starts. Change orders are the exception, and always in writing.

Layouts that give you back space

A lot of the gain in a bathroom remodel isn't square footage — it's how the square footage is arranged. Moving a door swing, swapping a bulky tub for a curbless shower, or floating the vanity a few inches off the floor can make a small room feel twice its size.

Before we quote anything, we map the drain lines and load-bearing walls. That tells us what can move cheaply and what would cost real money to relocate, so you can spend where it actually changes how the room feels.

The parts that decide how long it lasts

Two bathrooms can look identical on day one and be completely different five years later. The difference is behind the tile: the slope of the shower pan, the waterproof membrane, the quality of the valve, and whether the exhaust fan is actually sized for the room.

We build the wet areas as a system. That means a proper pre-slope, a bonded membrane, sealed penetrations, and moisture-rated materials in every spot that sees steam — so you're not repainting a peeling ceiling or chasing a hidden leak down the line.

Accessibility without the institutional look

Curbless entries, blocking for future grab bars, comfort-height toilets and slip-rated floors don't have to look clinical. Whether you're planning to stay in the home for decades or getting a rental ready for a wider range of tenants, we build in the practical features quietly, so the room still reads as a nice bathroom, not a hospital.

How it works

A process built around no surprises

01

Walk-through & measure

We look at the existing plumbing, the framing, and how you use the space, then talk through what's worth keeping and what isn't.

02

Design & fixed quote

You get a layout, a materials list, and a line-item price. Nothing is ordered until you've signed off.

03

Demolition & rough-in

We protect the rest of the house, tear out to the studs where needed, and rebuild the plumbing and electrical to code.

04

Waterproof, tile & finish

Membrane, tile, fixtures, paint and trim — the slow, careful part where the quality shows.

05

Final walk & warranty

We test everything with you, hand over the paperwork, and stand behind the labor in writing.

FAQ

Bathroom Remodeling — common questions

How long does a bathroom remodel take?

A standard full bathroom usually runs two to three weeks of on-site work once materials are in. We give you a day-by-day schedule up front so you know when the loud days and the quiet days are.

Can I use my bathroom during the work?

For a single-bathroom home we sequence the job to shorten the days it's fully out of service, and we're honest about which days that will be. In multi-bathroom homes it's rarely an issue.

Do you handle permits?

Yes. When the work touches plumbing, electrical or the structure, we pull the permits under our license and schedule the inspections. That paperwork protects you at resale.

What if we find water damage once the wall is open?

It happens in older homes. If we uncover rot or a hidden leak, we stop, show you exactly what we found, and price the repair before continuing — never a surprise on the final bill.

Do you offer a warranty?

Yes, our labor is warrantied in writing, and we pass through the manufacturer warranties on the fixtures and materials we install.

Reviews

What bathroom remodeling customers say

Im Happy
Meir Siboni
Irvine · garage door
They designed and built a paver patio and redid our front yard with drought-tolerant plants. Neighbors keep stopping to ask who did it. Couldn't be happier.

Added attic insulation and sealed the ducts. The upstairs bedrooms used to be an oven in the afternoon and now they actually stay cool. Great crew.
