How to install a shower base on a concrete floor

It is essential to understand that a lot of people use “shower pan, “shower base,” and “shower pan” to refer to the same thing. However, they’re two distinct entities. To install a shower base on the concrete floor, you must ensure that the concrete is level and clean.

Step 1

The shower base should lay on the floor to put it in and mark the outline. Take measurements of the length and width of the sump at the back of the shower base. Add an additional 20mm to ensure that there is enough room in which the ground can move and as well so that the bottom is still snugly in the floor. The distance between the sump and the sides of the base. Incorporate the sump measurements from the sides and utilize your level or spirit to mark the square in which it will cut a hole to allow the sump to fit in.

Step 2

In the corners, drill the square holes you’re carving to accommodate the sump. This will make it easier to cut it out. Wear safety glasses, gloves, and earmuffs, and use an angle grinder to remove the square from the fiber cement board. You have to take a hammer and an ax to cut out from the cement fibreboard, with the battery-powered saw cutting the next flooring. It may be necessary to use a handsaw to finish the cuts on the corners. The flooring should be lifted out. You might also have to use a handsaw to cut off any insulation present.

Step 3 

Place the shower base on the floor, and draw its height on the hardwood that it leans against. Take off the shower base. That pencil line on the wooden represents the highest point of the recess the shower base can fit into. Use a hammer, the chisel, or handsaw to cut the wood, forming cavities in the 10mm range to accommodate the shower base. Also, you’ll need to create an opening of 10mm in the lumber that runs along the width and length of the floor. Make this mark by marking 10mm away from the direction of the edge. Use the hammer and chisel to break the timber. Use gloves while keeping the wood to guard against scratches.

Step 4

Next, determine the level of your floor. This is vital since it can reveal the areas that, if there are any, may require additional cement to make sure the floor is level. Utilize the spirit level to measure the group across the width and length of the flooring.

Step 5

Make three portions of sand from bricks with one piece of mortar using the wheelbarrow to make your cement. Add water slowly to the mix and mix with your shovel to ensure it’s not too hard and not too fluid. Mix until it is of an even texture and consistency, and there aren’t any pockets of dry substance.

Step 6 

Utilize your shovel to place the concrete base onto the floor to cover all the bottom of the shower and give it the foundation it needs. If you’re required to put in more concrete in areas where it is necessary to ensure that the base of the shower is level when you place it in place.

Step 7

Place the shower base on the top of the concrete, then put it in place. Put it into the recesses that you cut out. After it’s set, use the spirit level to check its status. If it’s not, move it until it’s. Use your shovel to sweep off any excess cement along the edges of the shower base.

Step 8

To ensure that the shower’s lining is securely held in place, installing nogs inside the vertical screws is necessary. Take a measurement of the distance between studs, and then use your electrical saw, as well as a saw stool, cut the nags down to dimensions. Then, place the nogs above the shower base, and secure them all in place with the nail gun.

How to install a fiberglass base over concrete

Step 1

If you’d like to set up an outdoor shower on a concrete floor, a fiberglass stall would be perfect. Ideally, you’ll have a drain that is rough in, and the pipe will be just a few inches higher than the flooring. If not, you’ll need to cut into the concrete to run the new tube for a shower installation.

If you notice an untidy pipe and you are unsure of the cause, contact the contractor or plumber who performed it to verify that it is. The 2-in. pipe is often the drain for your tub or shower. It should line up precisely in line with your drain holes at the shower’s bottom bay. This is the position that determines the work that the walls of the studs will be surrounding the storm. The service provider might give an accurate sketch of the shower area, which means you don’t need to install it first.

Step 2

If the 2-in. drainpipe isn’t in the place you’d like it, you’ll need to cut the concrete into pieces and re-plumb the drain. The drainpipe should be at least an inch over the concrete. If the pipe is too small, you’ll need to break the concrete to extend it. Additionally, you’ll require at least 1 1/2-in. Space between the concrete and the pipe to allow the drainage system (see below for a photo). If not, you’ll need to remove any concrete around the line. If you’re thinking of a single-piece shower, ensure that you can fit it into the bathroom. It may be necessary to move the unit inside the toilet before framing the doorway and walls. If you have difficulty getting it in, consider multi-piece units that fit through doors more easily.

Step 3

Once you have framed the shower walls to match the shower bay, place the shower on its back and then install the drain for your shower. Install a special leakproof shower drain assembly called The No-Caulk Shower Drain. It is available in plumbing and home centers and plumbing supply stores. Although drain baskets can be plastic, I’d prefer the brass model. You can roll out a long coil (about the size of a pencil) from the plumber’s glue (available in all hardware stores) and then wrap it around the flange of the drain basket.

The shower drain basket should hold in place in the hole for the shower drain and then slide the washers on, thread them on and then tighten the outer setting ring. Then pull the round using a large slip-joint until it is securely fixed. You shouldn’t be able to move the shower basket with your hand. The putty from the plumber will squeeze out. Lower the shower area and basket over the drainpipe. Mark the pipe at least 3/4 inch. Beneath the drain basket flange.

Step 4

Lift the shower door off the floor to cut the drainpipe in length. Hacksaws are a great tool. Be sure that you cut the pipe in a square shape and not bent. Place the shower bay and the basket assembly over the pipe. Place the gasket that seals caulking over the line, and then press it down to ensure it rests on the lip at the drainage basket’s base. It may be necessary to tap the gasket to secure it using a hammer or a tiny bit of timber. Connect the caulking nuts and then tighten the nut to force the gasket into compression and close the pipe. Utilize the bar tool slotted included with the drainage assembly. Attach the flat blades of the screwdriver in the bar’s hole and then tighten the hand. Attach the drain cover with a perforated cover (not illustrated) ).

How to install a shower base on the concrete floor: Tips

  • Adjust the plate, making sure that it’s supported and at an even level to drain thoroughly before adding veneer to the rest of the wall or installing the screen.
  • Take off the plastic covering and then seal the entire area of the wall using non-molding silicone that is neutral, and let it sit for at least 24 hours before using the dish. Chemical silicone that comes into contact with plates may cause discoloration or even crack the word’s surface.
  • Make sure the base is set up correctly as well as drains correctly before beginning the installation of any other components. Plates cut and whose length is less than 900mm have to be placed on the cut portion embedded into the wall. Otherwise, the proper mounting of the screen is not possible.
