FAQ

What is the typical rough in for a bathtub drain?

When it comes to installing baths and showers, it’s important to consider the rough-in dimensions for the discharge/drain hole. In order to ensure proper drainage, the drain access opening should be positioned 10-14 inches away from the framing and be about 6-8 inches wide. For vertical drains located at floor height, the discharge/drain hole should be at a zero distance from the back wall. By following these guidelines, you can ensure a well-functioning and efficient drainage system for your bathroom fixtures.

What is the hole in the concrete slab under the bathtub?

These openings are typically left by plumbers for easy access in case the plumbing needs to be relocated or repaired. It’s important to note that bath traps can also serve as potential entry points for various pests such as termites, ants, millipedes, and certain cockroach species like the American and oriental cockroaches.

How deep should drain pipe be under slab?

The height of a house usually ranges from 18 inches to 3 feet, depending on factors such as location, building codes, and the frost line. The frost line refers to the depth at which the ground freezes during winter. By considering these factors, builders can determine the appropriate height for a house. For instance, houses in areas with a higher frost line may require deeper foundations to prevent damage from freezing and thawing cycles. Building codes also play a role in determining the height of a house, as they establish safety standards and guidelines for construction. Therefore, it is essential for builders to consider these factors when determining the height of a house to ensure its stability and durability.
