Bathtub Replacement: A Step-by-Step, Authoritative Guide

When it comes to updating your bathroom, few changes are as impactful as a bathtub replacement. Whether your tub is chipped, outdated, or just not functional for your lifestyle, replacing it is a strategic upgrade that adds comfort, value, and visual appeal to your space.

In the authoritative tone of David Visentin, here’s a no-nonsense, step-by-step guide to doing it right the first time.


Step 1: Assess the Current Bathtub

Before tearing anything out, evaluate the condition and type of your existing tub:

  • Is it built-in, freestanding, or part of a shower-tub combo?

  • Are there any structural issues, leaks, or water damage nearby?

  • Does the size or depth meet your needs?

Pro Tip: Replacing like-for-like is the most efficient route unless a complete bathroom reconfiguration is already planned.


Step 2: Choose the Right Replacement Tub

Consider the following types:

  • Alcove tubs: Ideal for smaller spaces, installed between three walls

  • Freestanding tubs: Visually striking, perfect for larger bathrooms

  • Drop-in or undermount tubs: Installed into a platform, great for spa-style settings

  • Walk-in tubs: Designed for accessibility and safety

Also weigh in on material options:

  • Acrylic: Lightweight and budget-friendly

  • Cast iron: Durable, retains heat well, but very heavy

  • Fiberglass: Economical, but less durable

  • Stone resin or solid surface: High-end look with great insulation


Step 3: Take Accurate Measurements

Measure the length, width, and depth of your existing space, including doorways and hallways for tub delivery.

Warning: A mismeasurement can derail an otherwise smooth renovation. Always double-check dimensions.


Step 4: Prepare the Bathroom for Demolition

Shut off the water supply and protect floors and fixtures. Demolition may involve removing tile, drywall, or surrounding enclosures.

Note: Be prepared for hidden damage. Water leaks or mold behind walls can add time and cost.


Step 5: Install Plumbing and Set the New Tub

Once the old tub is removed:

  • Ensure the subfloor is level and in good condition

  • Update the plumbing to match the new tub’s configuration

  • Set the tub securely using manufacturer-recommended supports

  • Confirm proper drainage and water flow

David’s Advice: Hire a licensed plumber for this phase unless you’re experienced with residential plumbing systems.


Step 6: Finish the Surround and Sealing

Install tile, panels, or other wall finishes. Then properly seal all edges with waterproof caulk to prevent future moisture damage.

Design Tip: Consider moisture-resistant materials like porcelain or natural stone for a lasting, stylish finish.


Step 7: Test and Clean

Once installation is complete, test all fixtures for leaks, ensure stability, and give the area a thorough cleaning.

Then… enjoy your new tub.


Final Thoughts

Replacing a bathtub is a substantial but worthwhile home improvement. Done properly, it can transform your bathroom into a more comfortable, attractive, and efficient space.

David Visentin’s Perspective: Focus on quality, planning, and execution—and you’ll get results that last.
