Step 2: Measure and Choose the Right Tub

Key considerations:

• Common tub sizes: 5 to 6 feet long, 30 to 36 inches wide

• Decide between styles:

Proper support is crucial:

• Secure the tub by attaching flanges to wall studs as per manufacturer guidelines

Step 5: Connect Drain and Overflow

To prevent leaks:

• Assemble the drain and overflow components using plumber’s putty or silicone caulk for seals

• Connect the tub drain to the home’s waste pipe system securely

• Test connections by running water and checking for leaks

• Tighten fittings if any seepage appears

Step 6: Install Surrounding Walls and Finishes

Finishing touches include:

• Installing drywall or cement board around the tub area
