Combined bathroom renovation - bathroom and toilet together

Combined bathroom renovation: what is different

In a separate bathroom and toilet, each room has its own role. In a combined bathroom, washing and the toilet are in one room, and there may be a washing machine too. Water from the shower can reach the toilet and the door, so the wet zone is the whole floor, not just the corner by the bath.

The manufacturer of Ceresit CL 51 intends this material for waterproofing walls and floors before tiling in bathrooms and showers. Waterproofing tape is applied at the joints between wall and floor, collars around pipes and drains, and corner pieces in the corners. In a bathroom and toilet there are many pipes: the toilet supply and sewage, the sink, the bath or shower, the washing machine, so every pipe crossing is a place where a collar is needed.

Layout in one room

• Shower with a drain or a bath: a shower takes less space, but the floor needs a slope.
• The toilet further from the shower zone or behind a glass wall, so that it stays dry.
• Washing machine: the water supply, the waste pipe and the socket before tiling.
• Risers: they are common property, stay in place, and a hatch is left by them.
• Ventilation: the natural extract duct grille is not covered.

If you are changing the electrical wiring in a wet room, it is installed under the supervision of a certified construction specialist, and the new installation needs residual current protection. A socket, switch or lighting point costs from €12 per point.

Combining or dividing

Some owners want to combine a separate toilet with the bathroom, others want to divide a combined bathroom into two rooms. In both cases it is replanning. According to the Riga municipality's explanation, to demolish a non-load-bearing wall when combining rooms, a certified architect prepares a plan and a construction notice is submitted in BIS. If a load-bearing wall is affected, an explanatory memorandum is needed. More on the page combining a bathroom with a toilet.

If the bathroom is moved to another place in the apartment, above the neighbour's living rooms this is permitted only if the requirements for soundproofing, waterproofing, thermal insulation, fire safety, ventilation and safety are met.

The order of work in a bathroom and toilet

1. Layout plan The positions of the shower or bath, toilet, sink and washing machine are marked.
2. Demolition All fixtures and finishes are removed.
3. Pipes and electrics Supply and sewage pipes are rerouted, sockets and light are installed.
4. Floor and waterproofing The floor is levelled, the slope towards the drain is formed, and waterproofing is applied to the whole floor and to the walls in the wet zone.
5. Tiles With Ceresit CM 17, the walls are grouted no sooner than after 12 hours and the floor after 24 hours.
6. Fixtures The toilet, sink, bath or shower and taps are installed.

After the renovation, for Ceresit CE 40 grout the manufacturer recommends washing the tiles with clean water only for the first five days.

How much a combined bathroom renovation costs

Prices are for labour. Materials are calculated separately in the estimate. The whole combined bathroom renovation, like a bathroom renovation, costs from €3,000. An example of individual jobs for a bathroom and toilet with 22 m² of surface to be tiled:

• tiling 22 m² × €24 = from €528;
• waterproofing 4 m² × €6 = from €24;
• replacing or installing a bath from €130 per bath;
• toilet installation during a renovation from €50 per toilet.

Together these four jobs are from €732, without demolition, pipes and materials. The price is affected by the room size, the condition of the walls, whether pipes, risers and electrical wiring are changed, and the chosen finish. All prices are on the page prices.
