How to Convert a Bathtub to a Standup Shower: Step-by-Step Instructions

Should You Hire a Professional or DIY?

When you convert a bathtub to a shower or add a bathroom, it can involve significant demolition, plumbing work, and installation. Removing the tub, rerouting pipes, and installing waterproof tiles are just a few of the challenging steps. While DIY may save on some costs, assuming no costly mistakes occur, it still requires careful planning, the right tools, and a solid understanding of plumbing and construction. Many homeowners hire professionals for bathroom makeovers to ensure quality results. Among those who choose to DIY the shower conversion, many still have professional plumbers reroute the pipes and call on handyman services for some of the bigger chores.

Planning the Conversion

• Assess the Space: Begin by assessing the available space. Will you choose a prefabricated shower or shower and tub combo for easy installation? Or will you opt for custom tiling to achieve a more personalized look?
• Evaluate Existing Plumbing: Confirm that your existing plumbing and drainage will accommodate the new shower. If not, reach out to a Neighborly service professional to retrofit the plumbing to support your shower. 
• Check Permit Requirements: Depending upon your location, you may require a permit for plumbing changes or structural modifications. If you hire a contractor to convert the bathtub to a shower, they typically handle the permit process. However, if you are doing it yourself, verify the permit requirements with your local building department before you begin.
• Plan for Material Disposal: Removing a bathtub creates a lot of debris, including heavy or bulky materials like cast iron, tile, and drywall. If you are doing a DIY tub-to-shower conversion, consider renting a dumpster to corral the waste. 

Removing the Bathtub

• Shut Off the Water: Turn off the water supply to avoid leaks or water damage during the tub removal.
• Detach Fixtures and Plumbing: Remove the faucet, spout, and drain. Disconnect any plumbing connected to the tub.
• Dismantle the Tub: Cut away any caulking or connections between the tub, walls, and floor. Remove the tub.

Prepare the Space

• Check the Space: Before proceeding, check for mold, mildew, or water damage. If you find any, have a reputable restoration service eliminate the mold and repair the damage.
• Reroute Plumbing: This is best done by professional plumbers.
• Deep Clean: Fully clean the space of all debris before installing the shower.

Install the Shower Base

• Install Shower Pan: Whether installing a prefabricated shower or laying in custom tile, the base must be securely installed and properly leveled to prevent leaks and ensure stability.

Installing Walls and Fixtures

• Install Walls: Use waterproof backer boards and appropriate growth for tiles to prevent water damage. Prefabricated panels should be properly secured and sealed.
• Attach Fixtures: Install the faucet, showerhead, and any additional fixtures like shelving.

Finishing Touches

• Doors or Curtain: Glass doors provide a sleek, modern look. Glass Doctor® specializes in custom glass showers and other types of bathroom glass and has awesome shower glass tips and ideas on their website. If your space is tight, a shower curtain may work better.
