FAQs
How long should I expect this bathtub installation project to take, and what's the estimated cost for materials?
For an intermediate DIYer, this project typically takes 2-3 days, allowing for demolition, installation, and drying times for mortar and sealants. Material costs can range from $300 to over $1000, largely depending on the style and quality of the new bathtub and drain assembly you choose, plus other necessary supplies like thinset and caulk.
What are the most critical safety measures I need to take during the demolition and installation phases of this bathtub replacement?
Always wear appropriate personal protective equipment (PPE), including safety glasses, work gloves, and a dust mask, especially during demolition. Before starting, ensure the water supply to the bathroom is shut off and any nearby electrical outlets are de-energized. Use proper lifting techniques or get assistance when moving the old and new bathtubs to prevent injury.
What are the most common errors when installing the drain and overflow assembly, and how can I ensure a leak-free connection?
The most common mistakes are not applying enough plumber's putty and failing to properly tighten connections. Generously apply plumber's putty to the underside of the drain flange and ensure all connections are hand-tightened, then given an additional quarter turn with an adjustable wrench or Channellock pliers. Thoroughly test for leaks with water before sealing up any walls.
Is a mortar bed absolutely necessary for setting a new bathtub, and what type of mortar should I use?
Yes, a mortar bed is crucial for properly supporting the tub's base, preventing flexing, and ensuring proper drainage. It distributes the weight evenly and prevents cracking over time. For this project, a thinset mortar like Custom Building Products VersaBond is suitable, mixed to a peanut butter-like consistency.
