When installing a shower pan, it is important to consider the type of mortar to use. While some sources recommend using a mix of standard cement with sand and Portland cement for its water-resistant properties, others suggest using Type S mortar for its strong bonding capabilities when mixed as a dry pack. However, Type S mortar is typically used for laying bricks and thinner applications, and mixing it too thick can make it difficult to work with. Ultimately, it is crucial to follow manufacturer guidelines and consult resources like the Tile Council of North America (TCNA) Handbook for best practices.

Type S mortar is not recommended for shower bases
The Sakrete company discourages the use of type S mortar for shower bases, stating that it is more appropriate for laying bricks.
However, some people have used type S mortar for their shower pans and pre-slope pans by mixing it as a dry pack. This allows it to bond well with a small amount of water.
The ideal mortar for a shower pan is a mix of standard cement with sand and Portland cement, as it creates a great water-resistant barrier that can support the weight of the shower unit.
Before installing a shower pan, it is important to ensure that the space can support the weight of the project. Basic support should be installed at the subfloor level, such as wire mesh or a paper slip sheet. The subbase should be supported on a wood frame, and the slope from the drain point to all perimeters should be calculated.

Type S mortar is good for thinner applications
Type S mortar is a versatile and commonly used mortar mix. It is suitable for a wide range of masonry projects, including those above and below grade. It is a general-purpose mortar with a high compressive strength of 1,800 psi, making it a good choice for thinner applications.
Thinner applications of mortar are often required in projects such as shower pans, where a waterproof barrier must be created between the shower bottom and the underlying layers. Type S mortar can be used for shower pans, but it is important to note that it should be mixed as a dry pack. This means using less water than usual, as Type S mortar is typically mixed quite wet for applications like bricklaying.
When creating a shower pan, it is crucial to ensure that the space can support the weight of the project. A subbase should be installed, supported by a wood frame. The drain point and height must also be identified, as the drain needs to be the lowest point. A general guideline is a 1/4-inch pitch per linear foot, but a greater gradient is also acceptable.
While Type S mortar can be used for shower pans, there are other types of mortar specifically designed for this purpose. A mix of standard cement with sand and Portland cement is often recommended for shower pans as it creates a water-resistant barrier that can support the weight of the shower unit. This type of mortar is also very shapable, allowing for a better fit with the shower pan.
In conclusion, Type S mortar can be used for thinner applications such as shower pans, but it must be mixed as a dry pack to achieve the required consistency. However, other types of mortar may be more suitable for this specific application due to their water-resistant and shapable properties.

Type N mortar is an alternative
Using Type S mortar for a shower pan is a topic of debate. Some people say that it is not suitable for shower bases and is more appropriate for laying bricks. However, others claim that it can be used if mixed as a dry pack. Type S mortar is a type of cement with sand in it, and it is important to distinguish between type S mortar and type S mortar cement.
When installing a shower pan, it is necessary to ensure that the space can support the weight of the project. Basic support at the subfloor level is required, which can be provided by a wood frame with wire mesh or a paper slip sheet. The subbase should be level, and the drain point and height should be identified to calculate the slope. A concrete layer is typically required to support the bottom piece of the shower pan, and a mortar mix is often used to create a shapable base that can accommodate the chosen shower or bath pan.
Some people have used a combination of mortar and other materials. For example, one person used a bag of LFT thinset mortar (the type for tile) along with a plastic liner above the wood subfloor. Another person used grout to install their shower pan, which they claimed has lasted for 16 years without shrinking like concrete or mortar.
It is always recommended to follow the manufacturer's instructions for the specific shower pan being installed.

The ideal mortar is a mix of standard cement, sand and Portland cement
There are differing opinions on whether Type S mortar is suitable for a shower bed. Some sources advise against it, while others claim it is suitable if mixed as a dry pack. However, the ideal mortar for a shower pan is a mix of standard cement with sand and Portland cement. This creates a water-resistant barrier that can support the weight of the shower unit.
Mortar is a mixture of sand and cement, used primarily for building brick or block walls. It is designed to be durable and achieve its strength through finesse. While cement, concrete, and mortar may be used interchangeably, there are distinct differences between them. Mortar is unique in that it does not contain large aggregates, which could reduce its overall strength but makes it more mouldable.
Portland cement is one of the most widely used building products globally, and mortar is a close second. Mortar can be made with the older method of combining Portland cement, hydrated lime, and fine sand. Alternatively, the newer method uses masonry cement and fine sand. The results are the same, and it often comes down to personal preference or regional availability.
There are several types of mortar, including Types M, S, N, and O, each with unique characteristics and applications. Type S mortar is a load-bearing mix, withstanding pressure from structures and external forces like soil, wind, and seismic activity. It has a high compressive strength of 1,800 psi, making it suitable for above and below-grade applications.
The standard cement, sand, and Portland cement mix recommended for shower pans combines the advantages of mortar's mouldability and water-resistance with the strength and wide availability of Portland cement. This combination creates an effective and durable base for a shower pan.
