Whitby has new subdivision homes with large ensuites and older streets in two heritage districts. Tile floors in both get cold in winter, which is why owners here ask about heat underfoot.
Yes, for most owners who are already replacing the floor tile. The heating mat costs far less to add during a renovation than at any later time. It needs its own circuit and a thermostat, and an ESA filing. If the floor tile is staying, it is usually not worth tearing up.
Brooklin is part of the Town of Whitby. Its permits come from the same Building Services Division as the rest of town. Downtown Brooklin's district counts 169 properties, each rated as contributing or not.
Downtown Brooklin has been a Heritage Conservation District since 2008. A new fan vent through a front wall or a changed window can need a heritage permit, so we ask the Town first. Heritage Planning staff handle most of these requests, and applying costs nothing.
Much of Brooklin was built since the mid 1990s, with an ensuite off the main bedroom. Those rooms are usually sound, so work centres on the shower, the vanity and the floor.
| Building permits | Town of Whitby Building Services Division. The Region plays no part in a house permit. |
|---|---|
| Plumbing changes | A drain that moves or a brand new bathroom needs a permit and inspections. |
| Heritage areas | Werden's Plan near downtown Whitby, and downtown Brooklin. Outside changes there may need a heritage permit. Werden's Plan alone covers 250 properties, and both district plans were renewed in 2026. |
| Heated floor | The circuit for the mat and thermostat is filed with the Electrical Safety Authority. |
| Our route | Close to 77 km east of the Oakville office, straight line, by the 407 or the 401. |
Ensuites in newer Whitby houses often have a corner tub nobody uses and a small shower beside it. Many owners trade both for one large walk-in shower.
Because the drains are close together, that change can stay simple. We still open the floor to check the slope before we promise a curbless entry.
Some builder fans vent into the attic on a short duct. The new fan runs to a roof or wall cap outside instead.
A heated mat fits neatly into this kind of job. The old tile has to come out for the new shower, so the subfloor is bare already.
Frosted ensuite windows often sit low beside the old tub deck. If the new shower wall covers part of one, resizing that window is permit work in Whitby.
A bathroom with a moved drain, a fixture in a new spot or a brand new room goes through the Town's E-Portal. These are the pieces we line up first.
Heated floors fail when they are rushed. These are the parts we never skip.
We check the mat with a meter when it arrives, once it is laid, and again after the tile is set.
Mats go in front of the vanity, toilet and shower, not under cabinets or the tub.
Set it to warm up before the morning rush and switch off after. That keeps the power bill small.
The electrician runs a dedicated line with ground fault protection. The ESA inspects it before the floor is closed.
Cold tile is a choice. Make it at the start, while the floor is open.
We show stock bathroom photos here for ideas only. We did not renovate the rooms you see in them.
