More than a new look

Fix the room that never quite dries.

In Hawaiʻi's humidity, an older bathroom is usually hiding something: grout that's given up, backer board that never dried, a tub wall someone climbs over every morning. We fix what's behind the tile first, then make it a room you actually want to be in.

  • Waterproofing you'll never see. Sealed membranes, moisture-resistant backer board, and the right drainage, built for the wettest sides of the island. It's the part that decides whether a bathroom lasts.
  • Safe for every age in the house. Curbless walk-in showers, slip-resistant porcelain, blocking for grab bars, and wider doorways, so kupuna stay safe and the room still looks like a bathroom you'd choose.
  • Plumbing and wiring by the right pros. A licensed plumber handles the plumbing and a licensed electrician the wiring. It's all in your written scope before we start, so nothing gets discovered mid-demo.

Designing for Oʻahu bathrooms

Make a small bathroom feel bigger, brighter, and calmer.

Light colors, calmer rooms

Soft sand and white tones with large-format tile open up a small hall bath. Deep gray-green and natural wood slow a primary bath down.

Lighting you can see by

Bright, even light at the mirror, a softer layer for evenings, and daylight where the room allows. No shadows where you shave or do makeup.

Walls that shrug off the damp

Moisture-resistant backer board under every tile, porcelain on top, and grout chosen for a room that gets steamy twice a day.

What to expect, week by week

Real start dates. Clean job sites. No surprises.

Standard baths · 7–15 days

New vanity, fresh tile, and a properly waterproofed shower in the existing footprint. In and out with the house still livable.

Primary suites · 3–4 weeks

Taken down to the studs, walls rebuilt and waterproofed, custom tile laid out for the room, and a walk-in shower you'll use every day.

Final walkthrough

We test the shower, check every grout line and seal, and walk the room with you. Nothing is finished until you say it is.

Questions, answered

Bathroom remodel questions, answered

How much does a bathroom remodel cost on Oʻahu?

Bathroom remodels with Island Contractors start at $25,000. We price every bathroom through the same three published tiers: Beautiful from $25,000, Impressive from $35,000, and Exquisite from $45,000, so you know what each level includes before the first conversation. The $250 on-site consultation is credited back to your project on contract, and if an older bathroom is hiding trouble behind the tile, we scope it honestly up front.

Do you do tub-to-shower conversions?

Yes, and it's one of the most common bathroom projects we do. We take out the old tub, rebuild and waterproof the wet area down to the studs, and set a walk-in shower sized to the room, curbless if you want no step at all. It makes a small bathroom feel bigger and makes mornings easier for every age in the house.

How long does a bathroom remodel take?

A standard bathroom usually takes 7 to 15 days. A primary suite taken down to the studs with custom tile runs closer to 3 to 4 weeks. The exact schedule depends on your tier, your tile and fixture lead times, and permit timing. You get a real start date in writing before we begin, and we hold it.

How do you handle moisture and waterproofing in Hawaiʻi's humidity?

We build the parts you can't see to the same standard as the parts you can. That means a sealed waterproofing membrane on the shower walls and floor, the right drainage, moisture-resistant backer board instead of plain drywall, and porcelain tile. Failed grout and soft spots behind old tile get fixed, not covered. Island humidity punishes shortcuts, and a bathroom that fails in five years was never a bargain.

Can you build a curbless or aging-in-place bathroom?

Yes. We build curbless walk-in showers with no step to trip over, add blocking in the walls for grab bars now or later, use slip-resistant porcelain, and widen doorways where the layout allows. It's designed to look like a clean, modern bathroom, so kupuna can stay in the home they love. Many multigenerational households on Oʻahu start here.
