Start with the bathroom you actually have. Many Surrey homes, especially the older ranchers and split-levels around Whalley, Guildford, and Newton, were built with compact bathrooms and standard tub alcoves. A good installer will measure the space, check whether your doorways and floor joists can handle the added weight of a filled tub, and confirm your hot water tank can keep up. Newer homes in South Surrey and Clayton often have more room to work with, but the plumbing questions are the same. Ask how they'll route drainage and whether any electrical work is needed for heated seats or air jets.
Prioritize installers with real experience fitting walk-in tubs for seniors, not just general bathroom renovators. Confirm they're licensed and insured in British Columbia, and read the fine print on the warranty, both the tub and the labour. The door seal is the part that matters most over time, so ask what happens if it ever leaks and how fast they respond to a service call. On features, we'd put a low or zero-threshold step-in first, then a quick-drain system so no one sits shivering while the water empties, a comfortable seat height, and an anti-scald valve with built-in grab bars.
Here's our honest take: pay for professional installation rather than a bargain fixture and a handyman. A walk-in tub is a permanent, plumbed-in piece of equipment, and a poor seal or an undersized drain turns a safety upgrade into a daily frustration. The cheaper route can look tempting, but the risk sits with the person using it every day. The trade-off is straightforward, a proper install with a specialist costs more up front, and you'll wait a little longer for scheduling. In our experience that's money and patience well spent. If budget is tight, ask whether the same firm also does grab bars or a curbless shower conversion, since those can be gentler on the wallet while you plan.
