What size should a walk-in shower be?

A walk-in shower should be at least 36" x 36" (3 feet by 3 feet) to meet building code requirements, but 48" x 36" or larger provides much better comfort and functionality.

The minimum dimensions are set by the Ontario Building Code, but most homeowners find these cramped for daily use. A 48" x 36" shower gives you enough room to move comfortably without feeling confined, while a 60" x 36" shower offers luxury-level space that's increasingly popular in Ottawa bathroom renovations.

Practical considerations play a big role in sizing decisions. If you're tall or prefer more elbow room, consider going wider rather than deeper - a 42" x 48" layout often works better than a narrow 30" x 60" design. For accessibility purposes, larger dimensions become even more important. Walk-in showers designed for aging in place or mobility aids should be at least 60" x 36" to accommodate shower seats, grab bars, and easier entry.

Ottawa homes often have space constraints, especially in older neighborhoods like the Glebe or Westboro where bathrooms tend to be smaller. In these situations, a corner walk-in shower can maximize your available space while still providing comfortable dimensions. Many Ottawa homeowners opt for 42" x 42" corner units as a good compromise between space efficiency and comfort.

Design tip: Remember that your shower will feel smaller once you add fixtures, built-in shelving, and glass doors. Always plan dimensions based on the clear interior space after accounting for these elements. The shower floor should also have proper slope (1/4" per foot) toward the drain, which your contractor will handle during installation.
