Bathroom Renovation in Ottawa — Built to Last, Designed for Your Life

Your bathroom gets used every single day. When the tile is cracked, the grout is stained, the layout is awkward, or the vanity is from 2002, it affects your whole morning. Trehane Renovation Inc. has been completing bathroom renovations across Ottawa since 2004 — full rebuilds, ensuite renovations, tub-to-shower conversions, and everything in between. We're a BBB-accredited, locally owned contractor that coordinates every trade involved so you deal with one team from demo to the final coat of grout sealer.

When Ottawa Homeowners Book a Bathroom Renovation

• The bathroom is original to a home built before 2000. Almond-coloured fixtures, cultured marble, fibreglass surrounds, and narrow shower stalls are the signature of late-1980s and 1990s Ottawa construction. Every suburb — Nepean, Barrhaven, Kanata — has thousands of these bathrooms, and their owners have been planning this renovation for years.
• Water got behind the tile and now there's a bigger problem. Failed caulking around a tub or shower surround is one of the most common causes of water damage in Ottawa homes. Once moisture is in the wall, the tile has to come off and the substrate has to be replaced. This turns a cosmetic job into a proper renovation — and it's the right time to do it properly.
• The layout wastes space. A toilet positioned so the door can't fully open, a shower too narrow to turn around in, a vanity that consumes the only floor space in the room — poor layout decisions made 30 years ago don't have to be permanent. We redesign layouts when the current one genuinely doesn't work.
• The house has only one full bathroom and the family has outgrown it. Adding a second full bathroom or a basement bathroom is one of the most effective ways to increase both livability and resale value in a family home.
• You're aging in place or planning ahead. Curbless shower entries, properly anchored grab bars, wider doorways, and comfort-height toilets make a bathroom safe and usable for decades to come. We install accessibility features that don't look institutional.
  

How Trehane Renovation Inc. Approaches Bathroom Renovations

The most important step in a bathroom renovation isn't the tile selection — it's the waterproofing. We apply a full waterproofing membrane system on all wet areas before any tile goes on. This is how we handle every project, because the cost of fixing a leak that develops behind finished tile five years from now is far greater than doing it right the first time.



Beyond waterproofing, we focus on trades sequencing — making sure plumbing rough-in is inspected and approved before walls close, electrical is done before tile starts, and tile is fully cured before fixtures are installed. Rushing that sequence is how projects end up with cracked grout lines and fixtures that leak at the connection point.

We've been working in Ottawa bathrooms since 2004 and understand the building conditions here: the older homes in the Glebe and Sandy Hill with plaster walls and cast-iron plumbing, the Nepean bungalows where every bathroom sits above a utility room, the Barrhaven builds where the master ensuite was clearly an afterthought in the original plan. Each situation calls for a slightly different approach, and that accumulated experience is part of what makes a project go smoothly.
