Building a mud pan requires several steps and a certain level of DIY skill. It is important to understand the process and the materials required to ensure a proper installation. The steps include creating a pre-sloped layer of deck mud, installing a waterproof membrane, and constructing a curb for the shower. The curb can be made using stacked 2x4s or bricks held together with thinset. The type of mixture used for the mud pan is also important, with some suggesting a combination of cement, sand, and mortar. The process can be time-consuming and labour-intensive, but it offers a unique handcrafted look and can save on costs compared to a pre-formed shower base.

What You'll Learn
Ensure a level perimeter and flat edges
Ensuring a level perimeter and flat edges is crucial when building a mud pan for a shower. A level perimeter and flat edges prevent issues with drainage and tiling. Here are the steps to achieve this:
First, it is important to have a pre-sloped layer of deck mud on the bottom. This deck mud should have a slope of 1/4" for every foot from the wall to the drain. The deck mud should be flush or slightly higher than the top of the bottom flange of the drain. This can be achieved by using a 2x4 or trowel to smooth out the pre-slope floor.
Next, you need to install a waterproof membrane or shower pan liner. This liner is sandwiched in the locking ring of the drain. After installing the liner, you can add a second layer of deck mud between the pan liner and tile.
It is also essential to build a curb for your shower. This can be done by stacking three 2x4s on top of each other, with the first one screwed into the floor. Additionally, you can cover the floor with metal lathe, which gives the pre-slope mud deck something to grab onto.
By following these steps, you can ensure that your mud pan has a level perimeter and flat edges, which are crucial for a functional and durable shower installation.

Use cement, sand and mortar
To build a mud pan using cement, sand, and mortar, you will need to follow these steps:
First, you need to create a sloped sub-base by cutting a piece of felt to fit the floor area between the bottom plates or float guides. Cut a section of metal lath to the same dimensions and nail or staple it securely to the floor. This gives the floor a "tooth" for the mortar to adhere to. You will also need to ensure that your subfloor is properly supported, replacing it with exterior plywood if needed.
Next, you will prepare the cement and sand mixture for the mortar bed. The standard ratio is 1 part cement to 4 or 5 parts sand, but this can vary from 4:1 to 6:1 depending on the consistency you desire. Mix this with a latex additive or water, being careful not to add too much liquid.
Now, it's time to spread the mortar onto the floor. Dump the mixture and use a wooden float to slope it from the top of the guides or the wall plate towards the drain. Pack the mortar down firmly with a 2x4 or a heavy trowel. The harder you pack it, the more solid the floor will be.
Let the mortar mixture dry for at least 24 hours or until it has completely changed colour and you can tell it is fully dry. This curing process may take several days, depending on the thickness of your mud pan.
After the mud dries, there will likely be some loose sand on the surface, which you can sweep or vacuum away. Do not continue to scrub or clean the surface beyond this point, as it will be difficult to stop.
Finally, you can smooth out the final mortar bed with a steel finishing trowel. This step allows tiles to be set directly onto the mortar bed without the need for additional thin-set mortar.
It is important to note that you should consult local building codes and relevant guidelines, such as the Tile Council of North America (TCNA) Handbook and ANSI108.1, before beginning this project. Additionally, waterproofing is crucial, so be sure to follow the manufacturer's instructions for installing a waterproofing membrane.

Install an isolation membrane
To install an isolation membrane for a mud pan, you will need to follow several steps. Firstly, prepare the subfloor by laying down a layer of felt paper. This will prevent the wood subfloor from absorbing moisture from the deck mud, which can cause it to dry too quickly and weaken the base. Cover the entire floor with metal lathe, overlapping any seams, and staple it to the floor. The metal lathe will give the deck mud something to adhere to.
Next, you will need to install the isolation membrane. A cleavage membrane made of poly or sheet membrane can be used. If you are using a pan liner, ensure that you do not use felt paper as the petroleum in the felt paper can react with the liner, causing it to crack or become brittle. Instead, you can use a product such as Oatey's Shower Pan Liner, which comes in CPE or PVC material. Mark the liner according to the measurements of your curb and cut it to size. Drape the liner over the mortar bed and drain base, ensuring that the edges are folded according to the application height. Cut X shapes over the bolts that the clamping ring screws into and a hole over the drain hole. Apply silicone caulk around the surface of the inner flange, then fold the liner back over and screw the clamping ring down.
Finally, you will add the deck mud. Use a 2x4 or trowel to smooth out the pre-slope floor, ensuring that the deck mud is flush or slightly higher than the top of the bottom flange of the drain. The deck mud should have a slope of 1/4" per foot between the drain and the wall.

Create a curb with 2x4s
Building a mud pan shower requires several steps, one of the first being building a curb to keep the water contained and prevent it from spilling out of the shower area. Here is a step-by-step process for creating a curb with 2x4s:
First, use a leveler to make a straight and level mark on the ground, then use a measuring tape to measure the length and width of the shower curb. Next, choose the planks you want to install. It is recommended to use three 2x4 cross-section planks, with two being standard wood and the other being thermal-treated wood. Gather the necessary tools, including two drill machines—one for drilling holes and the other for driving screws.
Now, place the liner carefully into the corners of the shower floor and curb. Position the edges of the liner up the side of the wall and use tape or nails to hold it in place. In the corners that are opposite the curb, fold the liner onto itself. At the curb edges, cut where the curb connects with the wall and lay the flag of the liner over the curb, ensuring it is completely covered. For added protection, use pan glue to hold the liner in place.
After that, take the first 2x4 plank and screw it into the floor. Place the second and third planks on top of the first, screwing them into place as well. Finally, take the previous plank and place it over the installed planks. Drill five holes in the plank from the corners and install standard screws into the wood.
Now you have a properly installed shower curb that will keep water from overflowing.

Waterproof with a shower pan liner
Waterproofing your shower is an important step that should not be overlooked. The shower pan liner is the most important aspect when it comes to waterproofing, as it protects the lower layers from water permeation and mould.
To begin, you will need to install an isolation membrane between the mud base and the basement slab. This will ensure that the shower pan is not structurally tied and bonded to the concrete, which could lead to cracks. 30-pound felt will do the job. Next, put down a layer of felt paper to prevent the subfloor from wicking moisture from the deck mud, which could cause it to dry too fast and weaken the base.
Now, you can install the shower pan liner. Oatey offers shower pan liner kits with either CPE or PVC sheet material. CPE is recommended if your floor has a radiant heat system. Fold the corners of the liner and staple it to the wall framing lengthwise. Add pan liner adhesive to the corners and staple it to the wall framing. Cut the liner at the inside corner and adhere it horizontally. Finally, staple the liner to the wall framing and cut away any excess.
After letting the adhesives cure overnight, test your work by pouring water into the shower bed at a height equal to the curb. Let the water sit for at least two hours. If the water level hasn't dropped and the surrounding area is dry, your shower bed is watertight.
