OUR SERVICES

More than a bathroom remodeling company in Costa Mesa

Primary Bathroom Renovation

Full transformation of your main bath – double vanities, freestanding tubs, oversized walk-in showers, heated floors, and the storage the original layout never had.

Guest & Hall Bathroom Remodel

The 5′ x 8′ hall bath is the most common bathroom in Costa Mesa, and the most commonly wasted. A pocket door, wall-hung vanity, recessed niches, and better lighting change how the entire room functions.

Wet Room & Curbless Shower Design

A fully waterproofed enclosure with no threshold to step over, a linear drain, and glass instead of a shower door. Beautiful, accessible, and completely dependent on getting the floor structure and slope right.

Tub-to-Shower Conversion & Accessible Design

Reclaiming a rarely used tub for a proper walk-in shower, with grab-bar blocking, comfort-height fixtures, and slip-resistant tile built in from the start rather than added awkwardly later.

HOW WE WORKs

3 easy steps to your new Costa Mesa bathroom

Bathrooms are small, sequential, and unforgiving of improvisation. Here’s how a Q Kitchen & Bath bathroom renovation moves from first visit to finished space.

01

We Visit You
At Home

We measure, check your existing plumbing and venting, look at the subfloor or slab conditions that determine whether a curbless shower is possible, and talk honestly about budget and how long you'll be without the room.
02

Design &
3D Renderings

You see the bathroom before demolition. Layout options, tile and fixture selections, realistic renderings, and a line-item proposal with fixed pricing and clearly stated allowances.
03

Permits &
Construction

We pull permits through the City of Costa Mesa, protect the rest of your home from dust, sequence trades tightly to keep the room out of service for as little time as possible, and manage every inspection to final sign-off.

Why bathroom remodels fail, and how we build differently

Q Kitchen & Bath serves Mesa Verde, Eastside Costa Mesa, Halecrest, College Park, the Westside, and South Coast Metro, along with Newport Beach, Irvine, Santa Ana, Huntington Beach, Fountain Valley, and surrounding Orange County communities.

Waterproofing is the whole job

Tile and grout alone aren’t waterproof. A properly installed membrane system with sealed seams, corners, and penetrations protects the framing and prevents hidden water damage. Q Kitchen & Bath focuses on proper waterproofing to help your bathroom last for years.

Ventilation that actually goes outside

An undersized exhaust fan, or one ducted into the attic instead of through the roof or exterior wall, is a mold problem waiting to happen. Fans need to be sized to the room, ducted to the outdoors with proper slope and insulation, and ideally run on a timer or humidity sensor. It's an inexpensive detail that prevents an expensive one

Curbless showers and floor structure

A curbless wet room needs the shower floor lower than the surrounding floor. In raised-foundation homes, this may require modifying joists; on slabs, the floor may need to be recessed or built up. These details should be addressed during design, not demolition, to ensure the structure is properly planned.

Current California fixture and electrical requirements

Bathroom remodels in California trigger requirements that older homes don't meet: GFCI protection at receptacles, high-efficacy lighting under Title 24, and state maximum flow rates on toilets, showerheads, and lavatory faucets. Permitted work gets inspected against these. Unpermitted work gets discovered during your escrow, at the worst possible moment.

FAQ

Costa Mesa bathroom remodeling questions, answered

A guest or hall bathroom typically takes 3 to 5 weeks of active construction. A primary bathroom runs 5 to 8 weeks, and projects involving layout changes, moved plumbing, or a curbless wet room can run 8 to 12 weeks. Add 2 to 4 weeks upfront for design, selections, and permitting. Tile installation is the phase that most often gets rushed by contractors trying to compress a schedule – and it’s the phase where rushing shows permanently.

In most cases, yes. Swapping a vanity or replacing a toilet in the same location generally doesn’t require one, but moving plumbing, altering electrical, adding or relocating an exhaust fan, or removing walls does – and that covers nearly every real bathroom renovation. Q Kitchen & Bath handles permitting through the City of Costa Mesa Building Division from plan preparation to final inspection. Unpermitted bathroom work is one of the most common issues flagged during a home sale.

For most Costa Mesa homeowners, yes – particularly in a primary bathroom. Walk-in showers are used daily, tubs in primary baths often aren’t, and the conversion typically makes the room feel considerably larger. The one caution is resale: buyers with young children generally want at least one bathtub in the house. If you have a guest or hall bath that still has a tub, converting the primary is a straightforward decision. If it’s your only tub, think it through before committing.

A wet room is a fully waterproofed area containing the shower – and often a freestanding tub – with no curb to step over, a linear drain, and typically a single glass panel instead of an enclosure. They look exceptional and they’re genuinely more accessible. Feasibility comes down to floor structure: the shower area has to sit lower than the surrounding floor, which means recessing the pan into the joists in a raised-foundation home, or depressing the slab or building up the floor on a slab foundation. We determine which applies to your home during the first visit.

Ask three specific questions before signing anything. First, which waterproofing system do they use, and is it a bonded membrane or an older liner method? Second, how do they treat inside corners, seams, and pipe penetrations? Third, do they perform a flood test on the pan before tiling? A contractor doing this properly will answer immediately and in detail, and many will show you photos of the work in progress. Vague answers on this subject are the clearest warning sign in bathroom remodeling – and you’ll be searching for a “bath remodel near me” again in five years if you ignore them.
