In the following sections, you’ll find everything you need to know to approach this project with clarity and confidence, making your bathroom renovation both efficient and effective.

Preparing the Area for Removal

Before removing the existing bathtub surround, it is essential to prepare the workspace thoroughly to ensure safety and efficiency. Begin by turning off the water supply to the tub to avoid any accidental leaks or water damage during the process. Remove any personal items, shower curtains, and fixtures such as soap dishes or towel bars that might obstruct the work area.

Next, protect the bathroom floor and nearby surfaces by laying down drop cloths or plastic sheeting. This helps to catch debris and simplifies cleanup. Use painter’s tape to mask off edges where the surround meets walls or the tub to prevent damage during removal. If the surround has caulking, soften it with a caulk remover or heat gun to ease separation.

Gather the necessary tools, which typically include:

  • Utility knife
  • Pry bar
  • Screwdriver (Phillips and flathead)
  • Putty knife
  • Hammer
  • Safety gloves and goggles

Wearing protective gloves and goggles is crucial to protect against sharp edges and debris. Once the area is prepared, you can proceed with carefully detaching the surround without damaging the underlying wall or tub.

Removing the Old Bathtub Surround

Start by cutting any caulking or sealant around the edges of the surround using a utility knife. This step helps break the seal and makes it easier to pry away the panels. If the surround is held in place with screws or nails, locate and remove them first.

Use a pry bar or putty knife to gently separate the surround from the wall. Work slowly and methodically, starting at the corners or seams, to avoid cracking the surround or damaging the drywall underneath. If the surround comes in panels, remove each panel individually.

Be mindful of plumbing fixtures; avoid applying excessive force near faucet handles or shower heads. After removing the surround, inspect the wall for damage or mold. Repair any drywall issues and ensure the wall surface is clean, dry, and smooth before proceeding to install the new surround.

Measuring and Selecting a Replacement Surround

Accurate measurements are vital when selecting a replacement bathtub surround to ensure a proper fit and a professional finish. Measure the height from the tub edge to the ceiling or desired surround height, and the width from wall to wall. Also, note any corners or irregularities that may affect the fit.

Bathtub surrounds come in various materials, including acrylic, fiberglass, PVC, and cultured marble. Consider the following factors when choosing a replacement:

  • Durability: Acrylic and fiberglass offer long-lasting resistance to moisture and impact.
  • Maintenance: Smooth, non-porous surfaces are easier to clean and resist mold.
  • Installation: Prefabricated panels simplify installation but may have limited sizes.
  • Aesthetics: Choose styles and colors that complement your bathroom decor.
  • Cost: Balance quality and budget for the best value.
Material Durability Maintenance Cost Range Installation Ease
Acrylic High Easy $$$ Moderate
Fiberglass Moderate Easy $$ Easy
PVC High Very Easy $ Easy
Cultured Marble High Moderate $$$$ Moderate

After selecting the material and size, verify that the replacement surround includes all necessary components such as corner pieces, trim, and adhesive.

Installing the New Bathtub Surround

Begin installation by ensuring the wall is completely dry, clean, and free of debris. If necessary, apply a waterproof backer board to improve moisture resistance and provide a solid mounting surface.

Dry-fit the surround panels to check alignment and make any necessary adjustments. Mark the locations for screws or anchors on the wall through the panel pre-drilled holes if applicable.

Apply adhesive recommended by the manufacturer evenly on the back of each panel. Press the panel firmly against the wall, starting from one side and working your way across to prevent air pockets. Use a level to confirm panels are straight.

Secure panels with screws or nails as specified. Seal all joints, edges, and corners with waterproof silicone caulk to prevent water infiltration. Smooth the caulk with a wet finger or tool for a neat finish.

Install any additional trim or accessories included with the surround kit. Finally, reattach plumbing fixtures, install new caulking around the tub edge, and clean the area thoroughly.

Essential Tips for a Successful Replacement

  • Always follow the manufacturer’s instructions for both removal and installation to maintain warranty coverage.
  • Use a stud finder to locate wall studs before securing panels for maximum stability.
  • If mold or water damage is detected behind the old surround, address these issues before installing the new unit.
  • Consider applying a waterproof membrane on the wall for added protection in high-moisture environments.
  • Take your time with caulking; improper sealing is a common source of leaks and damage.

By adhering to these guidelines, you ensure a durable, attractive, and waterproof bathtub surround replacement that enhances your bathroom’s functionality and appearance.

Preparing to Remove the Existing Bathtub Surround

Before beginning the removal of the old bathtub surround, thorough preparation is essential to ensure a smooth and safe process. Proper preparation minimizes potential damage to the underlying walls and plumbing and sets the stage for a successful installation of the new surround.

Start by gathering the necessary tools and materials. Typical tools include a utility knife, pry bar, putty knife, screwdriver, hammer, and safety gear such as gloves and goggles. Having these on hand prevents delays once removal begins.

Next, turn off the water supply to the bathtub to avoid leaks or water damage during the replacement process. Drain any residual water from the tub and surrounding plumbing.

Clear the bathroom of personal items, rugs, and furniture near the tub to provide unobstructed workspace. Lay down a drop cloth or protective sheeting to catch debris and protect flooring.

Inspect the existing surround for any caulking or sealant around the edges and seams. Use a utility knife to carefully cut through these seals, as this will facilitate easier removal and reduce damage to the drywall.

  • Gather tools: utility knife, pry bar, putty knife, screwdriver, hammer, gloves, goggles
  • Turn off water supply and drain tub
  • Remove personal items and cover floors
  • Score and cut through caulking and sealant

Removing the Old Bathtub Surround

Removing the old surround requires careful attention to avoid damaging the wall studs or plumbing behind it. Different types of surrounds—such as fiberglass, acrylic, or tile—may require slightly different approaches.

For prefabricated fiberglass or acrylic surrounds:

  • Locate and remove any screws or fasteners holding the surround in place. These are often hidden behind trim or caulk lines.
  • Use a utility knife to cut any remaining caulk or adhesive between the surround and the wall.
  • Gently pry the surround away from the wall using a putty knife and pry bar, starting at the edges and working inward.
  • Work slowly to prevent cracking or breaking the surround, which can cause sharp edges and debris.

For tiled surrounds:

  • Remove grout from between tiles using a grout saw or rotary tool.
  • Carefully chisel tiles away, starting at the edges and moving toward the center.
  • Remove the cement backer board or drywall behind the tiles if it is damaged or to prepare for the new surround.

Throughout the removal process, inspect the wall studs and plumbing for any signs of water damage or mold. Address any issues before proceeding with the new surround installation.

Preparing the Wall Surface for the New Surround

Once the old surround is removed, the wall surface must be properly prepared to ensure the new surround adheres correctly and remains waterproof.

Begin by cleaning the wall thoroughly to remove dust, adhesive residue, and debris. Use a scraper or sandpaper to smooth rough spots and remove any remaining caulk or glue.

Inspect the drywall or backer board. If the drywall is damaged or shows signs of mold or water damage, it must be replaced with a moisture-resistant material such as cement backer board or greenboard.

Ensure the wall surface is flat and even. Use a level to check for any unevenness that could affect the installation. Fill holes or gaps with appropriate patching compound and sand smooth after drying.

Apply a waterproof membrane or vapor barrier on the wall surface if the new surround system recommends it. This step is critical to prevent moisture penetration behind the surround.

Step Action Purpose
Cleaning Remove dust, glue, and debris Ensures good adhesion and surface quality
Inspection Check for water damage and mold Prevents future damage and health issues
Repair or Replace Patch holes or replace drywall with backer board Provides solid, moisture-resistant substrate
Waterproofing Apply vapor barrier or membrane Protects walls from moisture infiltration

Installing the New Bathtub Surround

Typical steps for installing a prefabricated surround include:

  • Dry-fit the surround panels to check alignment and make any necessary cuts for plumbing fixtures or vents.
  • Apply adhesive recommended by the manufacturer evenly on the back of the panels or on the wall surface.
  • Press the panels firmly into place, ensuring they are level and properly aligned.
  • Secure the panels to the wall studs with screws or nails as specified, typically through flange edges.
  • Seal all seams and edges with a high-quality, mildew-resistant silicone caulk to create a watertight barrier.

For tiled surrounds, installation involves:

  • Installing cement backer board over the wall studs.
