FAQ

How do upstairs bathrooms work?

In a two-story house, the plumbing system for the upstairs fixtures is situated beneath the concrete slab of the second floor. All the fixtures in the upstairs area, such as the shower, toilet, and basin, are connected to a single pipe known as a stack line. This stack line then connects to the main sewer drain of the house, which is located underground. This setup ensures that all the wastewater from the upstairs fixtures is effectively drained and disposed of.

Can a bathroom be added to a second floor?

Adding an upstairs bathroom to the second floor of your home during a renovation or redesign can greatly enhance its value. Whether you’re looking to increase the number of bathrooms or upgrade your master bedroom with an en suite, hiring an experienced designer can significantly add more value to your home with the addition of an upstairs bathroom.

What size should bathroom plumbing be?

The measurements for the toilet, sink, and shower/tub supply lines are as follows: – The vertical supply line should be 8 1/4 inches long and positioned 2 to 3 inches higher than the drain pipe. – The horizontal supply line should be a maximum of 6 inches from the center, with 4 inches to the left and right of the center. – The discharge/drain hole from the back wall should be 12 1/2 inches away. – There is no specific measurement for the discharge/drain hole vertically, but it is recommended to be positioned 16 to 20 inches above the floor.

Should bathrooms be above each other?

In some cases, it is common for a pair of bathrooms to be located side-by-side, sharing a common wall. This arrangement helps to minimize the need for separate supply and drain piping for each bathroom. In many instances, there is a main stack that efficiently carries waste from both bathrooms to the sewer system, ensuring proper disposal.
