Bathroom Renovations in Hamilton

Hamilton's housing covers the full range — 1920s and '30s villas and bungalows in the older suburbs, right through to the fast-growing new subdivisions in Rototuna, Flagstaff and Peacocke. As a family-run, NZCB-certified builder working across the heart of the Waikato, RB Thomas specialises in watertight, well-built bathrooms — from a single ensuite to a full main-bathroom rebuild. Whatever the condition of your Hamiltonhome or project, you get the same promise we’ve built our name on — projects on spec, on time, on budget.

What bathroom renovations looks like in Hamilton

Bathrooms are the most technical room in the house: get the waterproofing, falls and ventilation wrong and you're looking at rot down the track. For Hamilton bathroom renovations we do it properly — correct substrate, certified waterproofing, tanking, quality tiling, and the plumbing and electrical signed off by licensed trades. Whether it's a compact ensuite or a luxury main bathroom with a freestanding bath and walk-in shower, we manage the full job and leave you with a space that's built to last.

They said it, not us

I have had the privilege of using Jake as a builder and project manager on numerous occasions. I can honestly say you will never find a more honest and genuine man. His workmanship is second to none and he communicates through every step of the build/renovation and makes sure you understand the process. I couldn't recommend him highly enough.
