How deep should a soaking tub actually be?

A quality soaking tub should be 17-19 inches deep to provide proper water coverage for most adults, with 18 inches being the sweet spot for comfort and water efficiency.

Standard bathtubs are typically only 14-16 inches deep, which barely covers your legs when seated. True soaking tubs start at 17 inches and can go up to 24 inches for the deepest models. The extra depth allows water to reach your shoulders when seated, creating that spa-like soaking experience you're after.

For Ottawa homes, 18-inch depth works well because it provides excellent soaking while keeping water usage reasonable - important given our municipal water rates. Deeper tubs (20+ inches) hold significantly more water and may strain your water heater's capacity, especially in older homes with 40-gallon tanks.

Consider your bathroom's floor structure when planning a deep soaking tub. The additional water weight (about 60 pounds per cubic foot) may require floor reinforcement, particularly in older Ottawa homes or second-floor installations. A structural assessment ensures your floors can safely support the extra load.

Freestanding soaking tubs are popular choices for Ottawa bathroom renovations, offering flexibility in placement and often featuring the ideal 17-19 inch depth. Japanese-style soaking tubs go even deeper (22-24 inches) but require careful planning for plumbing and structural support.
