Why Do I Need To Know If My Installation Is A Barrier

For threshold installs, we recommend the drain run exactly wall-to-wall to block any water from leaving the shower or wet area. We do not recommend linear drains less than 2 wide or Tile Insert Frame linear drains for threshold installations without a curb due to the lack of channel width needed to sufficiently catch the water.

Installing a shower drain without a curb, barrier, or threshold creates a seamless look with easy accessibility to the wet area. To achieve an ideal installation, floor heights should be equal between the shower area , outside the shower , and next room.

Please consult a licensed professional when determining which installation is possible.

A Closer Look At A Two

When it comes to designing the perfect two-person shower, its all about what makes the couple the most comfortable. Some of the most common sizes for a two-person shower are 3 x 5 feet and 4 x 6 feet. However, some are even larger if space allows.

You also need two showerheads or a large overhead rainfall-style showerhead in a two-person shower. If you use two separate showerheads, you usually place them on opposite walls of the shower.

However, if you opt to place the showerheads on the same wall, position them at least three feet apart. Each person must have enough space to move around freely.

Another consideration for a two-person shower is the drain. A standard shower requires a minimum 2-inch drain pipe. However, since two people are using the shower, you might want to go with a 4-inch pipe to account for extra drainage.

The Dimensions Of A Walk

The ideal dimensions for your walk-in shower depend on a couple of things. First, you need to consider the overall size of your bathroom. You dont want your shower to overtake the space .

On the flip side, you dont want to make your shower too small for the people who will use it. There needs to be enough space for an adequate range of motion while showering.

According to the International Residential Code, the interior of a shower must be at least 30 by 30 inches square. However, the National Kitchen and Bath Association recommends a minimum interior shower space of 36 by 36 inches. Therefore, if your bathroom is on the smaller side, this might be the right size for you.

However, if you have more space to spare, 42 by 60 inches is a good size for one standing adult. This shower size provides more comfort with extra room to spread out a bit. Its also a more ideal minimum size for a walk-in shower.

Of course, if you can eke out a bit more space, even better. If you dont plan to use a barrier for overspray, your shower area should be 72 by 72 inches minimum.

Keeping Things Dry With A Walk


Since theres no curb to help contain the water, make sure your floor slopes toward the shower drain. The larger the shower, the gentler slope you can use.

Since you want the floor surface to have a seamless transition, you need to drop the subfloor in the shower. This way you can get a sufficiently deep mortar bed for your tile, at least 1 ½ to 2 inches. The top of the drain should set below the subfloor.

You might even want to consider adding an extra drain. Use a barrier for overspray where applicable, and consider a rainfall shower nozzle. Also, since its likely items in your bathroom will get wet, use waterproof lights and fixtures and non-slippery flooring. If possible, leave 6 feet of open space outside of your shower if you dont plan to use any barriers.

With no door to help keep steam in the shower, your bathroom is more susceptible to excess humidity. This can lead to mold growth, so its critical to install a good ventilation fan in your bathroom.

Measure Your Available Space

Shower size dimensions only account for interior shower space thus, a shower installation should take into account the complete amount of space available in the bathroom.

Because some shower alternatives have a minimum or maximum recommended height, measure the height of the area first. Then calculate the square footage by first determining the depth of the space, then the breadth.

The Dimensions Of A Standard Shower

The ideal size for a standard shower is 48 x36, but it can be as small as 30 x30. The latter size is the absolute minimum size for a shower. One of the most affordable shower choices is a prefab shower kit.

A standard shower is traditionally set up using enclosed panels and some type of shower door. These showers commonly feature a shower pan and either a framed or frameless glass panel enclosure. You can place various tile styles or other surfaces on the floor and walls to create unique designs.

You can purchase shower kits in various sizes, ranging from 36 to 42 inches square. Smaller kits, measuring 32 by 32 inches, can cost as low as $400. You can also find larger units, like 30 by 60 inches, for closer to $1,800.

These prices are for the shower and dont include any installation costs. With installation, a shower can run between $3,000 to $4,000. Of course, the bigger and fancier the shower, the higher the price.

Shower enclosures are a good option for small bathrooms since the panels help with overspray.

Shower Drain Tip #2 Dont Assume A Center Drain Is Best

In many tile installation forums, youll be advised to locate the drain in the center because its simplest to slope a tile shower drain in the middle to make the pitch consistent. However, in your common 48 x 36 size a center drain will also force you to stand smack dab in the middle of the drain. This not only isnt comfortable, its also downright nasty when your partner or family members hair causes the drain to CONSTANTLY be clogged!

First, I want you to know it doesnt have to be a pain to slope any drain. It CAN be easy whether its for a tile shower pan or a cultured stone shower base. You see for a tile pan you can buy a premade waterproof ready for tile base where the slope is already built for you . And with a cultured granite shower pan the slope is built into the pan with no tiles. AND the bonus is you can blow up cleaning grout joints FOREVER!

At the end of the day its best to locate the drain hole where itll work best for you. I recommend the drain be 12 from the shower head wall in front of you when showering . This keeps you from standing in the drain and pools of water when it gets clogged.

Linear Shower Drain Placement

How To Rough-In a Toilet (with Dimensions)

Homeowners like linear drains because they look very cool, and the shower floors don’t need to be sloped in more than one direction unless you install the drain in the middle. The writers at Easy Drain explain that you should place these kinds of drains against the wall in a three-sided installation, sloping towards it from all angles. These drains normally sit about 3 to 5 inches away from a shower’s wall. Before beginning any installation, it’s best to take measurements to ensure that you center the drain in its space.

A corner shower drain placement must also be at the lowest spot in the shower otherwise, the water will not drain properly, and you could wind up with some minor flooding every time you shower. It’s best to keep it a few inches from both corners so water doesn’t sit in the corner.

Does A Shower Drain Need A Trap

A trap is necessary to protect the shower drain from harmful substances in the sewer. Most shower drains come equipped with a P-trap which acts as a shield between microorganisms, toxins, and sewer gases to prevent them from entering your home. They also redirect the flow of wastewater away from your living place.

Why Choose A Linear Drain

Also called a trough or trench drain, a linear drain is a rectangular-shaped drain that allows for the use of larger format floor tile and the ability to pitch the floor in one direction. This offers an advantage from the traditional center drain installation, where the floor must slope in four directions in order to drain the water properly.

Benefits of a linear drain installation include:

  • No limitation on tile size or slab material
  • Can be placed as a threshold or curb
  • Meets ADA requirements for handicap shower entry
  • No boundaries on design because of the drain location
  • Drains water more efficiently
