Bathroom renovation plumbing

In a bathroom renovation, the plumbing is the part you stop seeing once the work is done — and the part that costs the most to redo if it was done badly.

Moving a toilet, adding a walk-in shower or installing a freestanding tub changes the drains and the supply, not just the finish. Drain slope, venting and outlet positions have to be settled before any tile goes down.

Our project photos show exactly this kind of work: freestanding tubs, glass showers, wall-hung toilets, supply fittings and chrome traps.

Does this sound familiar?

  • You are moving the toilet, tub or shower
  • You are converting a tub into a walk-in shower
  • You are installing a freestanding tub or wall-hung toilet
  • The existing drain has the wrong slope or size
  • The bathroom is in the basement, below street level
  • You are adding a bathroom where there was none

How we work

  1. We establish what is possible

    The position of existing drains and the floor structure determine what can move and at what cost. Better to know before choosing tile.

  2. We redo drains and supply

    Drains at the correct slope, proper venting, hot and cold supply renewed wherever accessible.

  3. We install the fixtures

    Tub, shower, toilet, vanity and fittings connected and commissioned, with visible traps and couplings done cleanly.

  4. We test before closing up

    Every joint is pressure-checked before walls and floor are closed — the only moment when a correction is still simple.

Frequently asked questions

Do you do the full renovation or just the plumbing?
We do the plumbing side: drains, venting, supply, and installing and connecting the fixtures. That is the portion that must be done by a licensed contractor, and the one the rest of the project depends on.
Can the toilet be moved?
Often yes, but it depends on the existing drain and the floor structure. The drain has to keep its slope and venting — that is what decides whether a move is simple or means opening the slab.
Is a basement bathroom possible?
Yes, but drainage needs particular care when fixtures sit below street level. Depending on the municipality, a backwater valve is required on connections receiving wastewater from basement fixtures.
Do you work with my general contractor?
Yes, that is common. We come in at the two usual points: rough plumbing before the walls close, then fixture installation at finishing.
