Bathroom Remodeling in Kailua
Kailua bathrooms come with a specific set of problems. A lot of the housing stock is older, much of it is single-wall construction, and everything within a few streets of the beach is quietly being eaten by salt air. We remodel bathrooms across Kailua, Enchanted Lake, Coconut Grove and Lanikai, and we price the job on what is actually behind the wall rather than what we hope is behind it.

Remodeling a bathroom in a single-wall Kailua home
A lot of older Kailua homes are single-wall — the exterior boards are the wall, with no stud cavity behind them. It is a Hawaii building method, it is common in the neighbourhoods built before the 1970s, and it changes a bathroom remodel more than most people expect.
There is nowhere to hide. Supply lines, drains and vents that a mainland contractor would run inside a wall cavity have to be planned differently. Mounting a heavy vanity or a grab bar means adding proper backing rather than hunting for a stud that is not there. Tile needs a substrate built for it, not fixed straight to boards.
This is why quotes for the same Kailua bathroom vary so wildly. A contractor who has not looked closely at the wall is guessing, and the guess gets corrected halfway through the job. We would rather find it on the estimate visit. That approach runs through our bathroom remodeling service wherever we work on the island.
If you are taking out a fibreglass tub-and-shower unit in an older Kailua house, tell us up front. That is a common Windward job and it is usually where the surprises live — see tub-to-shower conversion.
Salt air, and what it does to a Kailua bathroom
Close to the beach, the air is the problem. Salt gets into hardware, hinges, fixture finishes and fasteners, and it does not stop.
It shows up first on the things nobody thinks about when choosing a bathroom — the drawer runners, the door hinges, the screws holding a towel rail, the underside of a tap. A finish that lasts a decade in Mililani can look tired in a couple of years three streets back from Kailua Beach.
Choosing for that is straightforward once you know to do it, and it costs very little extra at the point of ordering. It costs a great deal to fix afterwards. Come to the showroom and we will show you the difference between hardware that survives out there and hardware that does not — start with bathroom vanities and tile.
Coastal permits in Kailua take longer. Plan for it.
A bathroom that changes nothing structural and moves no plumbing is permit-exempt — tile, vanity, fixtures in the same position, cabinets, countertops and finish work carry no valuation limit.
Move the toilet drain, relocate the sink, or add circuits and you need a permit. A permitted bathroom then brings current code with it: GFCI protection, proper venting, circuits brought up to standard.
And on the coast, the timeline changes completely. A standard residential review across Oahu runs four to eight weeks. Properties in the Special Management Area — which covers the coastal strip — run three to six months.
If you are close to the water, that is the single biggest thing standing between you and a finished bathroom, and it is worth knowing before you plan around a date.
Yes, we come over the Pali
Our showroom is in Kapolei, which is the other side of the island, and Windward homeowners are right to ask whether a West Oahu contractor will actually show up.
The most common complaint about contractors on this island is not price. It is that they do not call back. From r/Honolulu, January 2026:
"Find 5-7 to contact. Most will not return your call or show up to look at your place."
We serve Kailua as a normal part of our week, not as a favour — we have been serving Kailua alongside the rest of Oahu. You get a written estimate you can keep and read on your own time, without sitting through a sales meeting first, and one point of contact from design through final walkthrough.
Worth the drive to Kapolei, once
You only need to make the trip once. Open the actual cabinet doors, compare full countertop slabs instead of sample chips, and see the tile against the vanity before anything is ordered — including the salt-resistant hardware options that matter out here. Plan a visit to our Kapolei showroom.
Picking it in person is also how we avoid the most common failure in this trade, which is materials turning up wrong.
What a bathroom remodel costs in Kailua
Small bathrooms generally run $18,000 to $25,000. Larger bathrooms run $25,000 to $40,000.
Those are full remodels including materials and labour — not a starting price with the fittings left out.
The spread comes down to four things: whether the plumbing moves, what is actually behind the wall once it is open, whether the job needs a permit, and the finishes you choose.
Older single-wall homes sit higher in the range because there is more unknown behind the wall, and salt-resistant hardware is worth specifying near the beach.
One thing currently pushing material costs up island-wide: a 25% Section 232 tariff has applied to imported vanities and cabinets since October 2025. The scheduled increase to 50% was postponed to January 2027, so rates hold at 25% through 2026.
A bathroom we finished in Kailua
A Kailua bathroom where the old tub came out and a walk-in shower went in — the most common Windward job we take on.

An outdated bathtub turned into a walk-in shower, with white marble-look wall panels, a black-framed glass enclosure and a floating vanity with matte black fixtures.
We are a construction company, not a showroom
The showroom is where you choose materials. It is not the business.
Ward Design Center is a licensed general building contractor. We build room additions and ADUs, take on whole-home renovations, handle structural work, and run the job from design through to the final walkthrough with licensed trades for electrical and plumbing.
That matters for a bathroom, because the bathrooms that go wrong are the ones where somebody hit something structural and had to stop. When the wall comes down and there is a problem behind it, we are the people who can price it and fix it, not the people who have to call someone else and leave you waiting.
