Ensuring your tile shower is installed correctly starts with hiring a professional, experienced tile contractor. Look for someone with a solid reputation and positive reviews. It's also important to discuss the waterproofing methods they use. A well-installed shower should have a waterproof membrane behind the tiles to prevent water from reaching the underlying structure.

What is the best waterproofing system for a tile shower?

There are several effective waterproofing systems available for tile showers. Choosing the right one can make a significant difference in preventing water damage and ensuring the longevity of your shower. While there are many different shower waterproofing systems available, they mostly fit into the following categories:

Shower Liners

Shower liners are installed in the shower floor area, then appx 1.5” - 3” of mortar is placed over the liner. The tile is bonded to this mortar. This bed of mortar is generally called a “mud bed.”

With this system, any water that makes its way through the tile & grout will seep through the mud bed, where it will be captured by the liner and directed out the drain.

There are several types of liners used in tile shower installations to provide waterproofing beneath the mortar bed. Here are some of the most common shower liner materials:

• PVC Liners: These are durable plastic sheets installed over a pre-slope base and run up the walls to prevent water from leaking out of the shower area. PVC liners are effective but require careful installation to avoid punctures and ensure proper drainage.

• Hot Mop Liners: This traditional method involves applying layers of hot asphalt and tar paper to create a waterproof barrier. While effective, the process can be messy and requires skilled labor.

• Lead Liners: Once common, lead liners are now less frequently used due to health and environmental concerns. They are durable but heavy and require professional installation.

Waterproofing Membranes: 

Unlike liners, waterproofing membranes are installed over the mud bed or a pre-made foam shower pan. The tile is then bonded directly to the waterproofing membrane. With this system, any water that makes its way through the tile & grout will be immediately directed out drain by the waterproofing membrane.

Waterproofing membranes come in two main types: sheet membranes and liquid-applied membranes.

• Sheet Membranes: These large sheets of waterproof material, typically made from polyethylene, are applied directly to the substrate. The seams between the sheets are sealed with adhesive or special tapes to create a continuous barrier. Sheet membranes are highly effective and provide a reliable waterproofing solution.

• Liquid-Applied Membranes: These membranes are applied with a roller or brush and form a seamless, rubber-like coating when they dry. Liquid-applied membranes are versatile and can be used on various surfaces, including corners and edges. They are easy to apply and can cover irregular shapes, making them a popular choice for both DIY installations and professional use.

Which is better, a foam shower pan or a mud bed?

When it comes to creating the shower base, homeowners and tile installers have the option of choosing between a foam shower pan and a traditional mud bed. Each has its pros and cons, and the best choice depends on your specific needs and circumstances.

Foam Shower Pan

• Lightweight: Foam shower pans are significantly lighter than mud beds, making them easier to handle and install.

• Pre-Sloped: These pans come pre-sloped, ensuring proper drainage without the need for manual adjustment.

• Quick Installation: Installation is quicker compared to mud beds, which can save on labor costs.

• Consistency: The factory-made slope ensures uniformity and consistency in the installation.

Mud Bed

• Customizable: Mud beds can be shaped to fit any shower size and configuration, offering greater flexibility in design.

• Durability: When properly installed, mud beds are extremely durable and can support heavy loads.

• Material Cost: Although labor-intensive, the materials for a mud bed are generally less expensive than a foam pan.

• Experience Required: Installing a mud bed requires a skilled installer to ensure proper slope and stability.

What is the best mortar for a tile shower?

The type of mortar you use for a tile shower is crucial for ensuring strong adhesion and durability. The correct mortar for tile setting is thin-set mortar, which comes in two main types:

• Unmodified Thin-Set: This is a basic mix of cement, sand, and a water-retaining agent. It’s suitable for bonding tiles to the shower substrate and provides a strong, durable hold. Unmodified thin-set mortar is often used with waterproofing membranes that require this specific type of mortar.

• Modified Thin-Set: This type of thin-set mortar includes additional polymers, which improve adhesion and flexibility. Modified thin-set is especially useful for areas with high moisture exposure and temperature fluctuations, making it an excellent choice for tile showers.

  An important note: Some waterproofing membranes are not compatible with modified thin-set mortar, so be sure to verify mortar compatibility with your chosen waterproofing system.

What is the best grout for a tile shower?

Choosing the right grout is essential for both the appearance and durability of your tile shower. Here's a rundown of the best options:

• Epoxy Grout: Epoxy grout is highly resistant to water, stains, and chemicals, making it an excellent choice for showers. It is incredibly durable and doesn’t require sealing, which means less maintenance in the long run. However, it can be more challenging to work with due to its quick setting time and difficulty in application.

• Cement-Based Grout: This is the most common type of grout used in tile showers. It comes in two main varieties: sanded and unsanded. Sanded grout is used for wider joints (over 1/8 inch), while unsanded grout is suitable for narrower joints. Cement-based grout requires sealing to protect it from water and stains, which means more regular maintenance to ensure its longevity.

• Urethane Grout: Urethane grout is a relatively newer option that offers a unique blend of features. It is highly resistant to stains, water, and mildew, making it an excellent choice for high-moisture areas like showers. Urethane grout does not require sealing, similar to epoxy grout, which reduces the amount of maintenance needed. It also tends to be more flexible than cement-based grout, which can help prevent cracking. The downside is that urethane grout can be more expensive and may require professional installation to ensure proper application.

Should the corners in my tile shower be caulked or grouted?

The corners of your tile shower are particularly vulnerable to movement and cracking. The best approach to handle this is by using caulk, not grout, for the corners and edges. 

• Caulk: Caulk is flexible and can absorb movement without cracking. It is ideal for corners and edges where tiles meet because it accommodates the natural expansion and contraction that occurs over time. Silicone caulk is especially recommended for its waterproof and mold-resistant properties.

• Grout: Grout, while durable and strong, is not flexible. Using grout in corners can lead to cracks over time as the shower walls expand and contract. 

The industry standard, as defined by the Tile Council of North America (TCNA), is to use a 100% silicone caulk in any changes of plane (corners) in a tile installation.

What is the correct drain for a tile shower?

The drain is a crucial component in a tile shower, ensuring proper water removal and preventing pooling. It’s important to choose a drain that is compatible with the waterproofing system used in your shower. Here’s a look at how different types of drains fit with various waterproofing systems:

Drains for Waterproofing Liner Systems

In waterproofing liner systems, such as PVC or hot mop liners, the drain needs to integrate effectively with the liner. Typically, point drains with either round or square grates are used. These drains are usually positioned in the center of the shower floor. They must be compatible with the liner’s drain assembly to ensure a watertight seal. The drain should have a grate at the floor surface that captures the bulk of the shower water as well as a flange or connection that integrates with the the waterproofing liner under the mud bed, maintaining the system’s integrity.

Drains for Waterproofing Membrane Systems

For waterproofing membrane systems, such as sheet membranes or liquid-applied membranes, both linear drains and point drains can be used.

• Linear drains are generally installed along one edge of the shower floor, offering a sleek, modern look and making it easier to create a barrier-free, accessible shower. They require the floor to slope in one direction towards the drain, simplifying installation and ensuring proper drainage.

• Point drains can also be used with membrane systems. These drains are normally positioned centrally, with the floor sloping to this central location.

Drains for membrane systems require a specific type of connection to integrate with the waterproofing membrane. It’s crucial that the drain and waterproofing membrane are compatible to avoid issues like water bypassing the waterproof layer. Proper installation is key to ensuring that the drain maintains a continuous waterproof barrier.

How do I know if my tile shower floor is sloped properly?

Proper slope is critical for ensuring that water drains correctly from your shower floor. The general standard is to have a slope of 1/4 inch per foot towards the drain. This prevents water from pooling and causing potential water damage or mold growth.

• Visual Inspection: Look for areas where water tends to pool or doesn't drain efficiently. This can be an indicator of an improper slope.

• Use a Level: Place a level on the floor to check the slope. The bubble should show a slight incline towards the drain.

• Professional Assessment: If you’re unsure, a professional tile installer can assess and correct any slope issues to ensure proper drainage.
