Remove Old Tub: Turn off water, disconnect pipes, pry out tub, clean area
Before tackling the removal of your old tub, it's essential to understand the process as a critical step in transforming your bathroom. This phase demands precision, as improper handling can lead to water damage, structural issues, or personal injury. Start by turning off the water supply to the tub to prevent accidental flooding. Locate the shut-off valves beneath the tub or at the main water supply line, and turn them clockwise until they’re fully closed. If your home lacks individual shut-off valves, you may need to turn off the main water supply temporarily.
Once the water is off, disconnect the pipes attached to the tub. Use a wrench to loosen the couplings, but be cautious not to overtighten or damage the threads. Place a bucket under the pipes to catch any residual water, and consider wrapping the pipe ends with Teflon tape to prevent leaks during reinstallation. If the pipes are soldered, you’ll need a propane torch and solder remover to detach them safely. Always wear heat-resistant gloves and ensure proper ventilation when working with open flames.
Prying out the tub requires both strength and strategy. Begin by removing any caulk or silicone sealant around the tub’s edges using a utility knife or caulk removal tool. Next, use a pry bar to gently lift the tub from its base, working from one end to the other to avoid damaging the surrounding walls. If the tub is anchored to the floor or walls, remove the screws or bolts securing it in place. For heavier tubs, enlist a helper or use a furniture dolly to prevent strain or injury.
After removing the tub, clean the area thoroughly to prepare for the new installation. Scrub away any remaining caulk, soap scum, or mildew using a mixture of bleach and water or a commercial bathroom cleaner. Inspect the subfloor and walls for water damage, rot, or mold, addressing these issues before proceeding. If the subfloor is compromised, replace it with moisture-resistant plywood to ensure a stable foundation for your new shower or tub. This step not only enhances the longevity of your renovation but also ensures a clean, professional finish.

Prepare for New Unit: Measure space, check plumbing, ensure proper drainage and leveling
Before you fall in love with a sleek new shower unit, reality check: your bathroom space dictates the possibilities. Grab a tape measure and get intimate with your dimensions. Width, depth, and height are the holy trinity here. Don’t forget to account for door swing clearance and any obstructions like windows or vents. A common mistake is underestimating the space needed for shower doors or sliding panels. Pro tip: measure twice, order once. Most standard shower-tub combos range from 60 to 72 inches in length, but custom units can vary—know your numbers to avoid a costly mismatch.
Plumbing isn’t just pipes; it’s the lifeblood of your new unit. Locate your existing water supply lines and drain setup. Are they centered or offset? Copper, PVC, or PEX? If your new unit requires a different configuration, you’re looking at additional work. For instance, switching from a left-hand to a right-hand drain can complicate things. A plumber’s inspection can save you headaches later. Also, check water pressure—most showers operate optimally between 45 and 80 PSI. Low pressure? You might need a booster.
Drainage is where DIY dreams go to die if overlooked. Ensure your existing drain aligns with the new unit’s specifications. A misaligned drain can lead to leaks or improper sealing. Leveling is equally critical; an uneven base will cause water pooling and long-term damage. Use a level tool to check the floor slope—ideally, it should angle slightly toward the drain. If the floor is off, you’ll need to shim or adjust the subfloor. Ignoring this step is like building a house on sand—it’s only a matter of time before problems arise.
Here’s the kicker: preparation is 80% of the battle. Measuring, checking plumbing, and ensuring drainage and leveling aren’t just steps—they’re safeguards. They prevent costly mistakes, like realizing your dream unit won’t fit or discovering a leak weeks after installation. Think of it as the foundation of your project. Skimp here, and you’re setting yourself up for frustration. Invest time upfront, and the installation phase becomes a breeze. After all, a shower-tub combo isn’t just a fixture; it’s a daily sanctuary—make sure it’s built to last.

Install Shower Base: Apply adhesive, set base, secure edges, connect drain
Adhesive application is the linchpin of a secure shower base installation. Choose a high-quality, waterproof construction adhesive suitable for your subfloor material—typically a latex-modified thinset mortar or a polyurethane-based adhesive. Apply a generous, even bead along the perimeter of the subfloor, following the manufacturer’s recommended coverage rate (often 1/4 inch thick). Avoid over-applying, as excess adhesive can squeeze out and compromise the base’s stability. For added strength, apply a second bead in the center of the floor, creating a crosshatch pattern that ensures full contact between the base and subfloor.
Setting the shower base requires precision and patience. Carefully lower the base into place, ensuring it aligns perfectly with the drain hole and wall edges. Use a level to confirm the base is flat and pitched slightly toward the drain (approximately 1/4 inch per foot). If adjustments are needed, lift the base and add shims beneath it, avoiding direct placement under the adhesive beads. Allow the adhesive to cure for the recommended time—typically 24 hours—before proceeding. Rushing this step risks shifting the base, leading to leaks or structural failure.
Securing the edges is critical for waterproofing and longevity. Apply a bead of silicone caulk along the seam where the base meets the walls, smoothing it with a caulking tool or damp finger for a clean finish. For added protection, install a waterproof membrane (like PVC or CPE) behind the wall tiles, overlapping the base edges by at least 2 inches. This creates a secondary barrier against moisture intrusion. If your shower includes a curb, ensure it’s securely fastened to the base with screws and sealed with caulk to prevent water from seeping beneath it.
Connecting the drain is the final—and arguably most crucial—step. Ensure the drain assembly is compatible with your shower base and plumbing system. Apply plumber’s putty or silicone sealant to the underside of the drain flange, then insert it into the base’s drain hole from below. Tighten the drain securely, but avoid over-torquing, which can crack the base. Test the drain by pouring water into the shower and checking for leaks beneath the base. If leaks occur, disassemble the drain, reapply sealant, and retest until watertight. Proper drain installation ensures efficient water flow and prevents future plumbing issues.
By meticulously applying adhesive, setting the base, securing edges, and connecting the drain, you’ll create a sturdy, leak-free shower foundation. Each step builds on the last, requiring attention to detail and adherence to manufacturer guidelines. While time-consuming, this process transforms your tub-to-shower conversion into a functional, long-lasting upgrade.

Add Wall Surround: Attach panels, seal seams, ensure water resistance, trim edges
Attaching a wall surround is a transformative step in replacing a shower-tub combo, offering both aesthetic appeal and functional durability. Begin by selecting panels that complement your bathroom’s design—options range from sleek acrylic to textured stone-look composites. Measure the area carefully, accounting for fixtures like faucets and showerheads, and cut panels to fit using a utility knife or jigsaw. Secure the panels to the wall studs with screws or adhesive, ensuring they are level and plumb. This foundational step sets the stage for a seamless, professional finish.
Sealing seams is critical to prevent water infiltration, which can lead to mold, mildew, or structural damage. Apply a high-quality silicone caulk along all joints, using a caulking gun for precision. Smooth the caulk with a damp finger or tool to create a uniform bead, and allow it to cure fully according to the manufacturer’s instructions—typically 24 hours. For added protection, consider using a waterproof membrane behind the panels, especially in high-moisture areas. This dual-layer approach ensures long-term water resistance.
Ensuring water resistance goes beyond sealing seams; it involves thoughtful planning and material selection. Choose panels with built-in water barriers or opt for those made from non-porous materials like PVC or fiberglass. Test the installation by running water over the surround for several minutes, checking for leaks or seepage. Address any issues immediately, as even small gaps can compromise the system. Regular maintenance, such as reapplying caulk annually, will extend the surround’s lifespan.
Trimming edges is the final touch that elevates the installation from functional to polished. Use color-matched trim pieces to cover raw edges and create a clean transition between panels and adjacent surfaces. Secure trim with adhesive or screws, ensuring it aligns perfectly with the panels. For corners, consider using corner trim pieces designed to fit seamlessly, reducing the risk of water penetration. This attention to detail not only enhances the visual appeal but also reinforces the surround’s structural integrity.
In practice, adding a wall surround is a multi-step process that demands precision and patience. By attaching panels securely, sealing seams meticulously, ensuring water resistance through thoughtful material choices, and trimming edges with care, you create a shower space that is both beautiful and durable. This approach not only modernizes your bathroom but also protects your investment for years to come.

Connect Plumbing: Attach supply lines, test for leaks, install fixtures, turn water on
Attaching plumbing connections is a critical step in replacing a shower-tub combo, as it ensures functionality and prevents future issues. Begin by securing the supply lines to the new fixtures, using Teflon tape or pipe compound on threaded connections to create a watertight seal. For PEX or copper lines, consider using sharkbite fittings for a quicker, tool-free installation. Always align the lines properly to avoid kinks or strain on the joints. Once connected, double-check that all fittings are tight but not over-tightened, as this can damage the threads or seals.
Testing for leaks is non-negotiable and should be done before fully installing fixtures or turning the water back on. Start by capping the supply lines and filling them with water to check for drips at the connections. If using pressure, attach a pressure gauge to the system and pump it to 60–80 PSI, holding it for 15 minutes to ensure no leaks develop. For a simpler test, turn the water on briefly and inspect all joints for moisture. Even a small leak can lead to significant water damage over time, so address any issues immediately by tightening connections or replacing faulty parts.
Installing fixtures requires precision and attention to detail. Begin with the shower valve cartridge, ensuring it’s aligned with the hot and cold inlets. Secure the escutcheon plate and trim kit according to the manufacturer’s instructions, using silicone caulk to seal gaps between the wall and fixture. For the tub spout, apply pipe thread sealant and hand-tighten before using a wrench to secure it firmly. If installing a handheld showerhead, attach the hose to the diverter valve and test its flexibility and reach. Each fixture should be level and securely mounted to avoid wobbling or detachment.
Turning the water on is the final step, but it’s not as simple as flipping a valve. First, open the shut-off valves slowly to allow water to flow gradually, reducing pressure spikes that could dislodge connections. Turn on the faucet and showerhead to flush out debris and air from the lines, letting it run for 2–3 minutes. Check all connections again for leaks, paying close attention to areas where water pressure is highest. Once confirmed leak-free, adjust the temperature settings on the shower valve to ensure proper mixing. This phased approach minimizes the risk of sudden leaks and ensures the system operates smoothly from the start.
