Do I need a permit to remodel a bathroom in Costa Mesa?

In most cases. Costa Mesa expects a permit once plumbing or wiring changes, or when a tub is turned into a shower. New tile and a new vanity in the same spots may not need one. We tell you which it is and handle the paperwork.

Can you turn my tub into a walk-in shower?

Yes. It suits the smaller hall bathrooms in many 1950s and '60s Costa Mesa homes. We take the tub out, rebuild the floor and drain, waterproof everything and finish the shower in tile with a glass panel or door.

My bathroom has no exhaust fan. Can you add one?

Yes. We add a quiet fan vented to the outside, run by a humidity sensor so it turns on when it's needed.

Can you make my bathroom easier to use as we get older?

Yes. A curbless shower, a built-in bench, blocking for grab bars and a comfort-height toilet can all go in during the remodel.

How much does a bathroom remodel cost in Costa Mesa?

As a rough guide for Costa Mesa: $15,000 to $30,000 for a powder room, $20,000 to $35,000 to convert a tub to a shower, $30,000 to $60,000 for a full guest bath, and $60,000 or more for a primary bath. Swapping out old pipes adds to the total. You'll get an itemized number after we've seen the room.

How long does a bathroom remodel take?

A typical Costa Mesa bathroom is about 4 to 6 weeks of work once the permit is approved, and a simple tub-to-shower swap is often faster. Tile, glass and fixtures are on order before demolition starts.

Yanis Remodeling in Costa Mesa

Costa Mesa Bathrooms, Rebuilt from the Pipes Up

Yanis Remodeling is a family-owned remodeling company based in Irvine, right next door to Costa Mesa. For more than 15 years we've remodeled bathrooms across Orange County, from hall baths to full primary suites.

In older Costa Mesa homes, the bathroom often looks fine until the wall opens: old pipes, worn waterproofing, no fan. New tile over that won't last. We fix what's behind the walls first, then build the shower, vanity and storage you want.

One team handles the whole job, from design and permits to the final walkthrough, so you're not managing a plumber, a tile setter and a glass company yourself.

What Works in a Costa Mesa Bathroom

Older homes, small rooms and families sharing one bathroom. This is what we plan for.

Swap the tub for a walk-in shower

Many ranch-home bathrooms have a tub and shower in one, in a small room. A walk-in shower with a glass panel is easier to use and makes the room feel bigger.

Fix what's behind the tile

Older homes may have galvanized supply pipes and cast-iron drains near the end of their life. We replace them while the walls are open, then waterproof the shower properly before any tile goes up.

Add a fan that works

Some older bathrooms rely on a window instead of an exhaust fan. A quiet fan vented outside, on a humidity sensor, keeps mold and peeling paint away.

Make the shared bathroom easier

In a home with one or two bathrooms, a double vanity, more drawers and a shower that's easy to clean make mornings simpler.

Plan for later

A curbless shower, a built-in bench and blocking in the walls for grab bars cost little during a remodel and make the bathroom easier to use for years.

Permits & Approvals

Bathroom Permits in Costa Mesa, Handled

City building permit

Bathroom remodels that move a drain, turn a tub into a shower, change the electrical or open a wall need a permit from the City of Costa Mesa Building Safety Division. We prepare the drawings, submit them and book the inspections.

Lead and asbestos in older homes

Homes built before 1978 may have lead paint, and old tile, flooring, mastic or popcorn ceilings can contain asbestos. We test suspect materials before demolition and follow lead-safe work rules.

Water-saving fixtures

In homes built before 1994, which is most of Costa Mesa, California requires old high-flow toilets, showerheads and faucets to be replaced with water-saving ones before a remodel permit is signed off. We include this in the plan and the price.

HOA approval

Townhome and condo communities usually need HOA sign-off for work hours and anything that affects shared walls or plumbing. We get their requirements early.
