Preparing the Space and Removing the Tub
Before removing the existing tub, turn off the water supply to avoid leaks or flooding. Drain any remaining water from the pipes by opening the faucets. Remove any fixtures attached to the tub, such as the faucet handles, spout, and drain cover. This will give you clear access to the tub itself.
Next, protect the surrounding area by covering floors and nearby surfaces with drop cloths or plastic sheeting. Carefully remove the tub surround, whether it’s tile, fiberglass, or acrylic panels, by loosening screws or prying it off with a putty knife or pry bar. Take care to avoid damaging the walls or plumbing behind the surround.
Cut the caulk or sealant around the tub edges using a utility knife to separate it from the wall and floor. Disconnect the drain assembly by loosening the drain flange from the underside of the tub. You may need to remove the access panel behind the tub to reach the drain pipe.
Once all attachments are removed, the tub can be detached from the wall studs and floor. Most tubs are secured with nails or screws along the flange. Use a pry bar or reciprocating saw to carefully detach these fasteners. For heavy cast iron tubs, enlist help to avoid injury or damage.
Dispose of the old tub according to your local regulations. If the tub is fiberglass or acrylic, it may be cut into smaller pieces for easier removal. Cast iron tubs typically require professional removal services due to their weight.
Installing the Shower Base and Waterproofing
Select a shower base that fits the existing space and plumbing configuration. Shower pans come in various materials such as acrylic, fiberglass, or tile-ready mortar beds. Ensure the base has a proper slope to the drain for efficient water drainage.
Before installing the base, inspect and repair any damaged subfloor or framing. The floor must be level and sturdy to support the new shower. Use a level to confirm evenness and add shims or reinforcement where necessary.
Apply a waterproof membrane or liner to the subfloor and lower wall areas to prevent water damage. Common options include PVC liners, liquid-applied waterproofing membranes, or sheet membranes like Kerdi. Overlap seams and extend the membrane several inches up the walls.
Place the shower base onto the floor, aligning the drain hole with the plumbing stub-out. Secure the base according to the manufacturer’s instructions, which may involve screws, adhesive, or mortar. Confirm the base is level and stable.
Seal all joints between the shower base and the wall with waterproof caulk. This prevents water from seeping behind the walls or base. Allow the sealant to cure as directed before proceeding to wall installation.
Constructing Shower Walls and Installing Fixtures
Framing for new shower walls may require adjustments if the old tub surround framing was removed. Use moisture-resistant backer board or cement board as a substrate for tile or wall panels. These materials resist mold and provide a stable surface for finishes.
Install the backer board with corrosion-resistant screws, ensuring tight seams. Tape joints with fiberglass mesh tape and apply a waterproofing compound over the seams to enhance moisture resistance.
If using tile, apply a suitable tile adhesive and set tiles from the bottom up, maintaining consistent grout lines. For prefabricated panels, follow the manufacturer’s installation guidelines for secure mounting.
Install the shower valve, showerhead, and other fixtures after the wall finishing is complete. Position the valve at an accessible height and connect the plumbing lines securely, checking for leaks before closing walls completely.
Use a shower door or curtain to contain water within the shower area. Door installation requires careful measurement and mounting to ensure a watertight seal.
Maintenance Tips for Your New Shower
Regular maintenance extends the life of your shower and prevents costly repairs. Key practices include:
- Cleaning grout and sealant with non-abrasive cleaners to avoid damage.
- Inspecting caulk lines periodically and replacing cracked or missing caulk.
- Checking for leaks around fixtures and drain to catch issues early.
- Ventilating the bathroom to reduce moisture buildup and mold growth.
- Using a squeegee after showers to minimize water spots and soap scum.
| Maintenance Task | Recommended Frequency | Tools/Materials Needed |
|---|---|---|
| Clean grout and tiles | Weekly | Non-abrasive cleaner, soft brush |
| Inspect and replace caulk | Annually or as needed | Caulk remover, silicone caulk, caulking gun |
| Check fixtures for leaks | Monthly | Wrench, plumber’s tape |
| Ventilate bathroom | After each use | Exhaust fan or open window |
| Use squeegee | After each shower | Shower squeegee |
Preparing for Tub Removal and Shower Installation
Proper preparation is essential to ensure a smooth transition from a bathtub to a shower. This stage involves gathering necessary tools, assessing the existing plumbing, and planning the new shower layout.
Tools and materials needed:
- Adjustable wrench and pipe wrenches
- Reciprocating saw or oscillating multi-tool
- Hammer and pry bar
- Utility knife
- Measuring tape and level
- Plumbing supplies (pipes, fittings, valves)
- Shower base or pan
- Waterproofing membrane or backer board
- Tile or shower wall panels
- Silicone caulk and sealants
- Safety equipment (gloves, goggles, dust mask)
Assessment of existing plumbing and structure:
- Turn off the main water supply to prevent leaks during removal.
- Inspect the drain and water supply lines for compatibility with the new shower fixtures.
- Verify the floor structure beneath the tub for damage or rot; reinforce if necessary.
- Measure the tub area to determine the size and shape of the replacement shower base.
- Plan for the location of the shower drain, ensuring it aligns with existing plumbing or identify necessary adjustments.
Removing the Existing Bathtub
Removing a bathtub requires careful disassembly to avoid damaging surrounding walls and plumbing.
Step-by-step process:
- Disconnect plumbing: Remove the tub spout, faucet handles, and drain assembly. Detach water supply lines carefully.
- Remove surrounding wall finishes: Cut and remove drywall or tile around the tub apron to expose the tub flange and framing.
- Detach tub from wall framing: Locate and remove nails or screws securing the tub flange to the wall studs.
- Cut tub if necessary: For heavy cast iron tubs, use a reciprocating saw to cut the tub into manageable sections.
- Lift and remove the tub: Carefully extract the tub from the alcove, ensuring no damage to surrounding plumbing.
- Inspect the subfloor and plumbing: Check for water damage and leaks; repair or replace damaged components.
Installing the Shower Base and Waterproofing
A properly installed shower base combined with effective waterproofing prevents leaks and damage.
Selecting the shower base:
- Choose a prefabricated shower pan or construct a mortar bed base.
- Ensure the base fits the alcove dimensions and allows for proper drainage slope (typically 1/4 inch per foot).
- Verify that the drain opening aligns with existing plumbing or plan for adjustments.
Installation steps:
- Prepare the subfloor: Ensure it is clean, level, and structurally sound.
- Dry fit the shower base: Position the base to check fit and drain alignment.
- Apply mortar bed (if applicable): Spread a layer of mortar on the subfloor to create a stable, level bed for the base.
- Set the shower base: Press the base firmly into the mortar or onto the subfloor, ensuring the drain flange connects properly to the drain pipe.
- Seal the drain connection: Use plumber’s putty or silicone sealant to prevent leaks.
- Install waterproofing membrane or backer board: Apply a moisture barrier on the walls surrounding the shower area.
- Seal seams and corners: Use waterproof tape and sealant to protect joints between walls and shower base.
Installing Shower Fixtures and Wall Finishes
Once the shower base and waterproofing are in place, the next step is to install fixtures and finish the walls.
Fixture installation:
- Install the shower valve and control handle according to manufacturer instructions.
- Connect the showerhead arm and showerhead, ensuring secure plumbing connections.
- Test all water connections for leaks before closing walls.
Wall finishing options:
| Material | Advantages | Installation Notes |
|---|---|---|
| Tile | Durable, customizable, water-resistant | Requires waterproof backer board and grout sealing |
| Acrylic or Fiberglass Panels | Pre-formed, easy to clean, quick installation | Must seal joints and edges with waterproof caulk |
| Waterproof Wallboard (e.g., cement board) | Strong, mold-resistant, ideal for tile backing | Must be fully waterproofed with membrane or coating |
