Replace the bathtub with a shower cabin, following the reasoning of how many times a year we take a tub bath and how many times we shower, we propose removing the tub and replacing it with a cabin, which will also leave more useful space to move around or put furniture. One of the benefits of a shower cabin is that it allows comfortable entry into it, without the need to lift your legs; which is appreciated when a family member is elderly or has travel difficulties.

Materials to use:
· Silicone with transparent fungicide
· Porcelain adhesive
· Set
· Curved cabin
· Adhesive for ceramics
· Rubber cap

1 cut the tub seals and stonework

  • The first step in disassembling the tub is to cut the silicone seals or the material with which it was waterproofed. This procedure is done with a multifunction tool using its cutting blade.

  • With the same tool, cut the setting and adhesive from the stonework of the ceramics that are in contact with the tub.
  • This step should also be done if there is a soap dish attached to the wall.

2 eliminate ceramics

  • Use a combo and a chisel to remove the ceramic palmets that you marked in the previous step. This procedure is dirty, so it is recommended to constantly remove debris. Use a mask and glasses to protect yourself from suspended particles or those that could fly away.

3 remove the tub and support

  • After the previous step, the support of the tub will be exposed, most of the time made with wooden beams that form a structure where the tub rests nested. First disconnect the water inlet and drain pipe.
  • The procedure for removing it consists of unscrewing it, lifting it and moving it. This operation cannot be carried out by a single person. If the tub is in good condition, you can consider reusing it.

  • Without the tub in the bathroom, the floor and walls where it was placed are exposed, where most likely there is no ceramic coating. Remove everything that corresponds to the old installation and clean thoroughly when finished.

4 install the ceramics

  • The shower cabin is an implement that, unlike the bathtub, rests on a level and finished surface, so the next step is to cover the exposed areas (floor and wall) with ceramics.

  • The circular cuts to fit the water inlets and the drain outlets are made with an angle grinder with a diamond cutting disc. It is worn on the back of the palmette and then with a screwdriver the enamel part is broken.
  • You can see the installation of the ceramics in How to install ceramics?

5 identifies the pieces

  • This type of product comes packed in more than one box, where you can identify the frame (in this case aluminum), the tempered glass (with curved doors in our model) and the receptacle (the piece where the structure is placed, generally made of fiberglass). Also locate the manual to read before assembly, emphasizing the specific details of the product.

6 locate the receptacle

  • Present the receptacle in the location you have chosen, of course considering the position of the tub's water inlets and outlets.
  • The receptacle must be level, so adjust it by turning the plastic knobs on its legs. Use a spirit level to check that it is straight, it is not necessary to consider an extra inclination for the water to drain into the drain because it already comes with the necessary slope.

  • Connectto the flexible conduit that the receptacle has implemented, with the drain. And so that it is perfectly sealed, join both ducts using a rubber cap.

7 assemble the frame

  • The aluminum structure of a cabin must be assembled with the same screws that come with the kit you have chosen. Special care must be taken at the junctions between the vertical and horizontal pieces (the one we used for this project consists of four profiles, two straight and two curved), since the screws could bump into each other inside. Therefore, use the screws included in the kit and make the fixings only in the marks indicated on the pieces.

  • This particular product includes curved doors, so the vertex of the frame that will be the entrance to the cabin must have the paths along which the door cars will travel aligned.
  • After assembly, place the frame in its final position, without making any type of fixation yet.

8 assemble the fixed doors

  • In addition to its two sliding doors, this product has two straight tempered glass panels that are fixed on the sides, emerging from the parts of the frame that are attached to the walls perpendicularly. These aluminum pieces have a slot where you must first put a rubber that will seal the fit.
  • Insert the panel into the slot with the rubber, making sure that it is aligned along the entire length of the panel. The result should be a joint that does not vibrate or make sounds when handled.

  • Also install the seals on the outside of the panels. These will be the ones that will come into contact with the sliding doors.

9 Assemble the curved doors

  • The sliding system of the curved tempered glass doors is through cars that guide it along the paths that the structure has predetermined. For this reason, before joining these pieces to the rest of the cabin, these cars must be fixed to them. To fix the cars, identify the perforations in the curved glass, which are used to hook the cars, which in turn have a body made to function as a retainer.

  • Attach their respective vertical seals to the doors.
  • Hang the doors by hooking the top carriages into the slot in the frame. Those at the bottom have a small spring implemented that allows them to be fitted, remaining fixed in the same action.

10 fixes the panels and the shower column

  • For this procedure you must move the cabin until it allows you to work behind it. When you do this, be careful not to step on or strangle the flexible hose that goes under the receptacle.
  • On both sides of where the column will go, and attached to the two walls at the vertex of the corner where you will install the shower, are two smooth panels that are screwed to the frame at their vertical meeting.

  • Place the column in the place where it will go to make the water connections.
  • The column is fixed only to the sides, using the perforations that the glass panels already have and drilling the plastic from which the column is made. This operation is done with a drill and a 3 mm metal drill bit.

11 Test and seal

  • After checking that everything is in order, turn on the water in the house and test that the shower works correctly: that the water comes out through the column devices (in this case through the vertical shower, telephone and hydromassage jets). Carry out this process before sealing in case it is necessary to go back to correct.

  • Using anti-fungal silicone and a caulking gun, seal all areas where the tub is in contact with the floor, the wall, and the lower areas of the receptacle and the back of the tub.and the panels. Let dry for 24 hours before using the shower.
