Creating a bathroom in a small space requires a lot of trickery and meticulousness. Especially if you want to include a spacious shower, a vanity unit, a toilet and a towel radiator!

To create a complete bathroom in 5 m2

Practical tip

Refinished wood
This wood is heated at high temperature (about 280° C) to the limit of roasting.
This gives it a beautiful color much darker than natural and an inimitable odor. In addition, it becomes harder, rot-proof and offers good dimensional stability. On the other hand, its price is high!

  • To transform a holiday studio into a livable apartment in the year, it was necessary to exploit all the available space. This is how a small 5 m outdoor shed2but contiguous, was elevated to the rank of bathroom. The final atmosphere was to be both warm and refined. Not easy in so little place.
  • For the warm side, the walls, the floor and the vanity top, were covered with reshaped wood (Now, Retitech...) retained especially for its aesthetic qualities and its resistance to moisture. On the walls, a pine boards cladding 130 x 21 mm cut at the height of the piece, is screwed vertically on 27 x 27 mm treated fir battens. On the ground is glued a ash parquet 90 x 21 mm, as well as on the vanity top (65 x 21 mm blades).
  • The refined aspect is obtained thanks to the choice ofthe most refined equipment possible: faucet (HansGrohe), toilet and basin (Duravit), radiator (Acova). Finally, all unsightly elements (cumulus, pipes, flush, etc.) are cleverly concealed.
  • The water supply is made of copper and the evacuation PVC. Each adduction circuit is isolated from the installation by a quarter-turn valve. A water-repellent plasterboard wall (5 cm thick) serves as a separation between the cabinet and the shower. It also supports the washbasin and a window dedicated to let the light. Two large mirrorsone of 220 x 75 cm and the other of 110 x 100 cm visually enlarge the room.

Great preparation for small spaces

  • The horizontal cumulus of 150 l is fixed to the wall by injection dowels, flush with the ceiling, and above the future washbasin. However, the security group descending still too low, he is deported to a closet in the next room. Thanks to this trick, a height of 1.80 m is kept in relation to the ground. Subsequently the dressing of the balloon is fixed on a wooden frame.
  • The plumbing in copper tubes is fully created and the reductions in water supply are made as soon as possible to limit piping noise. The apartment is located on the ground floor and, by chance, the wastewater evacuation passes under the floor slab. After opening the latter to the chipper, the duct is caught with 100 mm panties for the toilet and a 50 mm saddle for the sink and the shower tray.

  • For the washbasinOnce the plumbing is in place, the plasterboard wall is raised to a height of 78 cm. In this way, the rim of the basin supported by this support rises to 93 cm from the ground. The 3 cm thick water-resistant chipboard is, on the shower side, placed on the wall and on the other side, on a cleat pegged to the wall. The cladding boards are then simply glued with polyurethane putty and the holes necessary for the passage of the evacuation as well as the feed are provided by the jigsaw or the hole saw.

Hot, dressing!

  • Supporting frame of the cladding, cleats are pegged horizontally on the walls, every 50 cm approximately. The blades are fixed by two screws on each batten. Their spacing is everywhere the same. The holes are pre-drilled and countersunk to a depth of about 5 mm in order to conceal the screw heads with a trunnion. At the fixing lugs of the towel radiator, the frame is doubled to support the weight of the device.
  • The space between the cladding and the wall allows hide piping and electrical conduits. Thin insulation may be interposed if the wall faces out. The outlets of the electrical outlets and sconces are drilled in progress.
  • The mirrors above the basin and on the opposite wall are glued to the mastic and double-sided adhesive on a strictly flat 5 mm plywood, painted and sanded. The installation of the non-centered basin releases a large space on the plan, as well as the column tap installed at an angle. The vanity top is separated from the shower by an 8mm tempered glass wall. It remains only to ask the taken and the appliques.

The cumulus and its formwork

Cumulus formwork

  • The cumulus is fixed flush with the ceiling using lag screws of 190 x 14 mm.
  • The formwork displays a setback in front to gain a little height and to fix the fixtures.

The washbasin with mirror

Glue the plaster tiles

  • Before gluing the plaster tiles previously cut to size, insert a special plastic sole to isolate them from moisture.
  • Check the plumbness and horizontality of the spirit level.

Lay the chipboard on the wall

  • Lay the waterproof chipboard on the wall and on a peg board on the opposite wall. It will serve as a support for the reefed ash blades.
  • Screw it on each side and cut out the siphon passage.

Screw the fixing rods of the basin

  • Present the bowl to identify the cuts to be made in the washroom.
  • Then screw its fixing rods.
  • Also drill the location of the valve with a hole saw or flat drill.

Screw the aluminum rail receiving the glass

  • Screw the aluminum rail receiving the glass between the basin and the shower, before installing the coating. It will be used to align the wooden boards, the other end disappearing under the wall covering.

Glue the boards with putty-glue

  • Glue the blades to the polyurethane glue mastic starting at the front.
  • Temporarily fix a board to the edge to make it easier to adjust the first blade and the next edge band.

Cut out the siphon and tap location

  • Cut into the blades the siphon and faucet location.
  • Apply a silicone sealant seal in the grooves to seal.
  • Do not fix the last blade to facilitate the installation of the mirror.

Screw the plywood panel onto the framing

  • The collage of the mirror requires a perfectly flat and healthy background.
  • Screw the plywood panel onto the framework and check its flatness with a ruler.
  • Apply two coats of matte paint to block the bottom.

The profiles where the separating glass is inserted are screwed into their supports. Shims 2 mm thick. are glued in the bottom and a bed of silicone sealant is extruded lengthwise before the glass is applied.

Apply a bead of caulk under the basin

  • Place under the basin a bead of mastic, without excess to avoid overflowing.
  • Turn the sink over and turn it on after checking the siphon for proper positioning.

Connect the hoses to the mains

  • After positioning the faucet, clamp the bottom of the toilet, not forgetting the seal and the washer.
  • Connect the hoses to the water supply.

Place special glue on the back of the mirror

  • Place special glue beads and double-sided adhesive tape on the back of the mirror to hold it during setting.
  • Bring suction cups to put it in place.

The towel radiator

Hang the radiator

  • Given the weight of the radiator, anchor the supports directly to the frame.
  • Check horizontality, then hang the unit.

Connect the radiator to the power supply

  • Connect the radiator to the power supply.
  • Do the same with the sconces and the catches.

The toilet is suspended

The suspended toilet is placed close to an angle. The support frame with built-in tank 6/3 l (Clara) is chosen freestanding, because it is here impossible to anchor it to the wall. It is then dressed with pinned pine screwed from the back on a chipboard of 10 mm.

A side hatch provides access to the tank shutoff valve. The evacuation is done through a flexible connection called "accordion" (Wirquin).

Simple to install, it is glued to the exhaust pipe side, but just nested on the outlet of the bowl.

Screw the support frame of the toilet.

  • Screw the support frame to the ground with four 8 x 80 mm lag screws.
  • Prepare the drain hose to receive the accordion fitting from the bowl. The height of this is adjustable in 12.5 mm increments.

Conduct a positioning test of the toilet.

  • Perform a positioning and operation test (evacuation).
  • Restart and proceed with the wooden cladding of the frame.
  • Reserve the location of the control plate and then connect it.
