The order of your bathroom renovation should prevent damage to the completed work. Start with demolition and removing the old fixtures. Then, address structural repairs or water damage, if needed. Next, tackle the rough-in phase for plumbing and electrical work, install waterproofing, and work on wall treatments like tile or paint. Install your shower or bathtub, toilet, vanity, and sink. Flooring goes in after major fixtures but before the toilet. Lastly, install new lighting fixtures, mirrors, and other finishing touches as desired.

There are several ways to save money on a bathroom remodel through proper planning and savvy design strategies. To reduce costs, consider the following:

• Purchase your own materials: Buy your own bathroom fixtures, hardware, and other materials to avoid contractor upcharges and delivery fees.

• Shop smart for big-ticket items: Save on pricey items like tiles and tubs by shopping sales and at discount stores.

• Avoid major layout changes: Keep plumbing in its current location. Opt to replace fixtures rather than moving them to avoid significant renovation work.

• Focus on high-impact, low-cost updates: Make affordable but impactful smaller changes, such as upgrading hardware, installing new lighting, and adding stylish but economical accessories.

• DIY where possible: Handle easier parts of the remodel yourself, like painting or installing light fixtures, to save on labor costs.

• Time your remodel strategically: Consider remodeling in the spring, which tends to be a lower-demand time of year and may result in lower costs.

You can put a structure under your bathtub for support. Many modern tubs come with a built-in support structure underneath. Almost any type of mortar or floor-leveling compound is acceptable for new bathtubs that don’t include a support structure.

You can also install spray foam under an existing bathtub to eliminate or reduce squeaking or sagging. However, spray foam isn’t rigid enough for primary tub support.

To keep a walk-in tub in good condition, clean it regularly with non-abrasive cleaners. It is also important to periodically inspect the seals, jets, and faucets to ensure they are functioning correctly.
