asked in category: General Last Updated: 8th May, 2020# How much slope should a bathroom floor have?

**floor should have**a

**slope**no greater than 2%, or 1/4 inch vertical drop per 12 horizontal inches. Measure the height of the drain with the tape measure. Calculate your

**slope**from there to the exterior edge of your room. You

**need**1/4 inch of

**slope**for each and every linear foot of

**floor**space.

Similarly one may ask, how much fall should a bathroom floor have?

**Floor** falls For **bathroom floors**, the **recommended** minimum **fall** to the waste shall be 1:100 (10mm per 1m). For shower areas with a vertical separation between the shower area and the wet area, such as a shower screen, hob, set-down or water stop, the **fall** to the waste shall be 1:100.

how much slope should a shower floor have? **Shower Floor Slope** To efficiently drain, the recommended minimum **slope** for a **shower floor** is about 4 percent, or a 1/2 inch drop per every 12 inches from the **shower** walls to the drain. In traditional tile **shower** construction, this **slope** is established in the mortar pre-**pan**.

Also, how do you Slope a bathroom floor?

The preferred **slope** is between one-quarter and one-eighth inch per running foot of **floor** length. As a rule of thumb, all areas around the drain should have a similar **slope**. To calculate this, multiply the length in feet of the farthest wall from the drain and multiply that result by 0.125.

What is the minimum slope for water drainage?

The **minimum slope** that I recommend is two percent, or 1/4 inch per foot. As an example, the grade at a spot four feet away from your house should be one inch lower than the grade next to your house. This will do for most houses with soil that will absorb **water** readily.
