The shower curb is an important element in any bathroom, as it helps to keep water from spilling out onto the floor. But should the shower curb be sloped?
While there are differing opinions on the matter, many experts believe that a sloped shower curb can help improve drainage and prevent water from pooling.
In this article, we’ll explore the pros and cons of sloping your shower curb and provide some tips on how to do it properly.
- Sloping a shower curb is essential to prevent water damage and improve accessibility.
- The type of shower pan, desired slope angle, and building codes must be considered when designing a sloped shower curb.
- Proper maintenance and care can help prolong the life of your shower curb and prevent costly repairs.
Understanding Shower Curbs
1. Role of a Shower Curb
A shower curb is a raised edge that surrounds the shower floor and prevents water from flowing out of the shower area.
It is an essential component of any shower as it helps to keep the water contained within the shower and prevents it from spilling onto the bathroom floor.
The shower curb also provides a barrier for the shower door or curtain to rest on, keeping it in place and preventing water from escaping.
2. Types of Shower Curbs
There are two types of shower curbs: pre-made shower curbs and manufactured shower curbs.
Pre-made shower curbs are typically made of concrete and are installed during the construction of the shower. They are often covered in tile to match the shower walls and floor.
Manufactured shower curbs are made of materials like PVC or fiberglass and are designed to be installed on top of the shower floor. They come in a variety of shapes and sizes to fit different shower configurations.
3. Height for a Shower Curb
The height of a shower curb is an important consideration when designing a shower.
The ideal shower curb height is 2″ above the top of the drain, or as short as 1 ¼” if you have a ¼” per foot slope.
Shower curb height refers to the drop off between the top of the drain and the curb, and they cannot be higher than 9″. Showers with a big slant or slope require short curbs, and level showers require a taller curb.
4. Shower Thresholds
A shower threshold is the transition between the shower floor and the bathroom floor.
It is important to ensure that the shower threshold is properly sloped to prevent water from escaping the shower area.
The slope of the shower threshold should be between 1/4″ – 1/2″ per foot, depending on the type of shower pan used.
A properly sloped shower threshold will direct water toward the drain and prevent it from spilling onto the bathroom floor.
5. Curbless Showers
Curbless showers are becoming increasingly popular in modern bathroom design. They eliminate the need for a shower curb, providing a seamless transition between the shower floor and the bathroom floor.
However, a slope is still required to ensure proper drainage. The slope for a curbless shower should be between 1/4″ – 1/2″ per foot, depending on the type of shower pan used.
THREE Reasons Why Sloping a Shower Curb Is Important
In this section, we will discuss the importance of sloping a shower curb and the benefits it provides.
1. Water Drainage
Sloping the shower curb ensures that water drains correctly and with enough force to clear all the water from the shower. Without proper drainage, water can accumulate, leading to flooding, water damage, and mold growth.
A properly sloped shower curb should slope at least 1/4 inch for every 12 inches for the most effective and safe water drainage.
2. Preventing Water Damage
Sloping the shower curb is important to prevent water damage to the bathroom floor and other areas surrounding the shower.
Without a proper slope, water can pool up and damage the shower or bathroom floor.
Water damage can be costly to repair, and it can also pose a health hazard due to mold growth.
To prevent water damage, it is essential to ensure that the shower curb is sloped correctly. A sloped shower curb acts as a barrier that prevents water from seeping out onto the bathroom floor.
3. Safety Considerations
Sloping the shower curb is also essential for safety in the bathroom. A level or flat shower floor can be dangerous, as it increases the risk of slips and falls.
A properly sloped shower curb ensures that water drains away from the shower entrance, reducing the risk of slips and falls.
In addition to preventing slips and falls, a sloped shower curb also helps to regulate water pressure. A shower floor that is not sloped correctly can cause water to accumulate, leading to high water pressure that can be dangerous.
TWO Shower Curb Materials and Installation Tips
1. Choosing the Right Material
When it comes to choosing the right material for your shower curb, there are several options available.
Tile is a popular choice for shower curbs as it is durable, water-resistant, and easy to clean. It also gives you the flexibility to choose from a variety of colors, patterns, and designs. However, it requires proper waterproofing and installation to prevent water damage.
Fiberglass and acrylic are also popular choices for shower curbs as they are lightweight, easy to install, and require minimal maintenance. They are also available in a variety of colors and designs, making it easy to match the rest of your bathroom décor.
Kerdi-board is a newer material that is gaining popularity due to its waterproofing properties. It is made of lightweight foam and is covered with a waterproof membrane, making it an ideal choice for shower curbs.
2. Installation Process
The installation process for a sloped shower curb involves several steps. First, you need to choose the right material for your shower curb. Once you have chosen the material, you need to prepare the shower pan and walls for installation.
If you are using tile for your shower curb, you will need to install metal lath over the shower pan and walls to provide a secure base for the tile.
You will then need to mix and apply mortar to the lath and install the tile. Once the tile is installed, you will need to apply grout to fill in the gaps between the tiles.
If you are using fiberglass or acrylic for your shower curb, the installation process is much simpler. You will need to measure and cut the material to fit the size of your shower curb and then attach it to the shower pan and walls using adhesive.
Regardless of the material you choose, it is important to ensure that the shower curb is properly sloped to allow water to drain into the shower pan. The ideal slope for a shower curb is between 1/4″ – 1/2″ per foot, which allows the water to be directed away from the shower area and down the drain.
Overall, choosing the right material and following the proper installation process is crucial for ensuring that your shower curb is comfortable, durable, and water-resistant.
Shower Curb Sizes and Building Regulations
1. Determining the Right Size
When it comes to determining the size of your shower curb, there are a few factors you need to consider. One of the most important things to think about is the slope of your shower floor.
If you have a curbless shower, you’ll need to make sure that the slope of your shower floor is between 1/4″ to 1/2″ per foot. This will help ensure that water is directed away from the shower area and down the drain.
If you have a shower stall with a curb, you’ll need to make sure that the height of your curb is appropriate.
According to building codes in most locations, shower curbs should be at least 2 inches above the top of the drain. However, the ideal height for your shower curb will depend on the slope of your shower floor.
In some cases, a curb as short as 1 1/4″ may be appropriate if you have a 1/4″ per foot slope.
2. Complying with Building Codes
It’s important to make sure that your shower curb complies with all relevant building codes.
Building codes vary by location, so it’s important to check with your local building department to ensure that you’re following the rules. In most cases, building codes require shower curbs to be at least 2 inches above the top of the drain.
If you’re building a shower for someone with disabilities, you may need to comply with ADA accessibility requirements.
According to the ADA, a standard shower must be at least 36×36 inches. However, the International Residential Code allows for a shower size of 30×30 inches, which is often used in smaller bathrooms to conserve space.
Here’s a table summarizing the standard shower sizes as per ADA and International Residential Code:
