Does the pointing between the tile and the Unidrain frame have to be hard or soft? (silicone)?
When pointing between the components/building parts of different material, normally soft pointing is used to avoid crack formation with dissimilar movements.This also applies to pointing between the Unidrian frame and the tiles. Nevertheless, the majority prefer to use hard pointing as this is better looking and matches the surrounding floor. By using hard pointing around the Unidrain frame, there is a risk of small cracks in the pointing, which along the way must be repaired. Purely in terms of function and density there is no problem since the frame is "isolated" in the drain.
Note! Silicone pointing must also be maintained/replaced over time.
Can I fit a Unidrain myself (Do It Yourself = DIY)
Yes, partially. Compared to a traditional floor drain, Unidrain is easy to install, among others because a Unidrain can be fixed/screwed during the entire building process - and because the entire floor construction is easier since only a one-sided slope needs to be made.
Fitting/building-in can be carried out as DIY work.
Connection to the pipe system must be carried out by an authorised sewer contractor or plumbing and heating fitter, all depending on the type of installation.
I am about to removate my current shower cubicle, which has an internal width of 940 mm (raw wall before tiles), which I cannot change. I would like to use Unidrain. What do I do?
Since your cubicle measurements do not fit a wall-to-wall solution (unit type 1001), then the solution is to choose unit type 1004 in length model 800 mm (is physically 900 mm floor flanges, which ensures overlap for the lubrication membrane). The frame for unit 1004.0800 measures 780 mm.
Let us assume that your wall tile (incl. membrane and tile cement) is 10 mm thick, so your finished shower cubicle width will be 920 mm (940 mm - 2x10 mm). The distance from the side walls to the Unidrain (the frame) will be: 920 mm – 780 mm (frame measurement)/2 = 70 mm.
How is the frame fitted into the unit?
When you are ready to lay tiles, the frame is quite simply put loosely in place in the unit. Floor and wall tiles are laid over the Unidrain's horizontal and vertical flanges (where the membrane is also applied) with a point distance to the frame. After this pointing is done around the frame.
Note! The frame is "open" (not fixed to the unit) so that water that seeps through any leakages in the pointing/tiles can escape under the frame and into the drain. See also the question below.l!
How much should the floor slope?
On a traditionally built bathroom floor (shower cubicle), with a four-sided slope, you calculate on a slope of min. 1 cm per metre.
With Unidrain, a one-sided slope is made which is far more simpler to make and simultaneously gives a completely level floor. With a completely level floor, there are no depressions and irregularities that have to be dealt with, which is why the requirement for slope is reduced: > 0,5 cm. per metre.
If I want to install a 900 mm Unidrain system that runs from wall to wall in the shower cubicle (Fitting1001.0900), which width measurement must be allocated for the cubicle?
It is very simple. Your width measurement must be precisely 900 mm as the unit's external measurement is precisely 900 mm. Note that this concerns finished wall measurements (plastered wall, wet room gypsum, etc.) before tiling as the tiles (and wet room membrane) must be placed down over the unit's vertical flange. The measurement of your finished shower cubicle is thus 900 mm minus the thickness of your wall tiles incl. membrane and tile cement.
Unidrain was the first on the market with the new type of line drain, but I have now seen several other drains, which are apparently exactly the same. Since I will be renovating three bathrooms in my house and make a great deal out of choosing the right solutions, my question is therefore:
Why should I choose Unidrain as the drain solution?
You are correct - Unidrain invented the line drain (and later the corner drain), which was introduced in 2003 as somewhat of a world novelty.
You should choose Unidrain because:
- Unidrain has a unique patented wall flange system (ensures waterproofing against walls)
- Unidrain is thought-out quality with high finish
- Unidrain is simple to install (few parts)
- Unidrain is modern, stylish design
Unidrain has 100 % focus on the "new standard in floor drains" - we are the ones who set it - and this means commitment!
Can Unidrain be ordered for special measurements?
No, but Unidrain is available in a number of standard length models and types, which can often cover the majority of needs. Furthermore, the modular system (drain systems over 1400 mm) which are made up of 2 drain units with set module measurements. Here, it isi possible to a certain degree, to vary the total length via choice of length models (as well as number of units that are combined)).
Can one purchase directly from Unidrain as a private individual or fitter?
No - In order to ensure availability, Unidrain is distributed through all plumbing wholesalers, building markets, tile stores, etc. This means that you can purchase Unidrain where you normally purchase building materials. Everyone is of course, welcome to contact Unidrain with questions, for advice or technical service.
In which lengths can I obtain a drain unit?
Unidrain drain units (line) is supplied in the lengths 300 mm, 700 mm, 800 mm, 900 mm and 1000 mm. If a longer drain is required, e.g. for larger washing facilities, Unidrain has a modular system which begins at 1400 mm and can be combined in various lengths.
Why do I have to choose a strainer?
The strainer is calculated to capture hair and small items that fall through the grate and possibly collected in the drain trap. In this way, a better flow through the drain trap is ensured and less frequent cleaning of this (removable).
Note! The strainer is not suitable for installations with heavy loads as this will require far too frequent cleaning (e.g. public washing rooms like swimming centres, schools, sports halls, etc.).
How do I choose outlet unit?
All outlet units for the 1000 line system fit all unit types in this system (as well as units in the 1100 module system). The choice of outlet unit is quite dependent on the construction task - i.e. technical options/requirements. For the choice of outlet unit for the 2000 corner system, the same applies.
How do I choose the grate?
Choice of grate is exclusively a question of length model as well as taste. With the choice of design, you should also think about the overall style of the bathroom (tiles, sanitary appliances, mixer taps, furniture).
How do I choose the frame?
The frame follows the unit type. When you have chosen the unit, the frame type is obvious (see question above about unit choice).
Unit 1001 uses 1501 frame
Unit 1002 uses 1502 frame
Unit 1003 uses 1503 frame
Unit 1004 uses 1504 frame
Unit 1005 uses 1505 frame
With a specified frame type, you choose the frame length (model) that is the same as the unit's length model. Finally, the frame height is chosen according to the tile thickness that is to be used on the floor. (Remember to take consideration of tile cement which increases the "tile thickness").
How do I choose the correct components?
With the choice of components, the following considerations should be included:
What will the shower cubicle look like?
Which technical connection options/requests are there?
Which tiles/floor tiles will be used on the floor?
Which design best suits the rest of the style in the bathroom?
With these considerations in place, the choice of components is almost obvious - see also the questions about choice of the individual components.
How do I choose the fitting (drain)?
Choice of unit depends on the shower cubicle's appearance/construction:
1001 is used if the shower cubicle has permanent side walls and the unit is to be from wall to wall (assuming the module measurement fits the shower cubicle).
1002 is used if the shower cubicle has permanent side wall to the left and for example a glass wall/open space to the right.
1003 is used if the shower cubicle has a permanent side wall to the right and for example, a glass wall /open space to the left.
1004 is used where it is necessary/required to keep a distance from the side wall.
1005 is typically used as a traditional floor drain, for example under the basin, in utility room, etc. (can also be used in the shower cubicle).
2001 (Corner) is typically used in smaller shower cubicles, but in principle in all places where a particuarly discreet corner design is required.
How many components are included in a Unidrain system?
In order to obtain a complete system, 4 components must always be used. Unit, outlet unit, frame and grate. A strainer is available as an accesory.
Which frame heights can I obtain?
Currently, Unidrain supplies frames in the heights 8, 10 and 12 mm.
Is there one single order number that covers a complete system (set) - that is, all four components?
No - The Unidrain system is very flexible and can, to a high degree, be adapted to the individual customer's needs. The system can be combined in so many ways that in practice it is impossible to have one single product number.
Is there a difference between the grates - that is, besides the grate pattern /design?
No – All the grates have, for a given length model, the same measurements and specifications: 3mm solid stainless steel with brushed surface finish
A grate in a given length model will fit all types of drain units/frames in the same length model. The price is also the same..
Can Unidrain be used for bathrooms with vinyl?
Unidrain is provisionally only intended for floor tiles/tiles.
(A vinyl solution requires a special clamp frame for anchoring of the vinyl)
Can one obtain a Unidrain calculated for free placement in the floor - that is, not a wall placement?
No - Unidrain's philosophy is to move the drain away from the floor/treading surface and out to the wall. This gives a number of advantages, e.g. one-side slope (simple floor construction), option to use large tiles, totally level floor, etc. By moving the drain out into the room, minimum two-sided slope must be constructed, often three or four-sided slope.
Can I use Unidrain on the 1st floor in a wooden construction?
Yes - Unidrain is approved for fitting in wooden and concrete constructions (light and heavy constuction).
Note! With fitting in timber beam layers, the outlet unit must be supported
I am about to renovate my bathroom and have chosen a Unidrain line system for the shower cubicle. Since we are to have a bathrub and washing machine in the room and do not wish to establish more drains, the question is: Can a Unidrain be used as a central drain?
Yes - the outlet units 1403.0075 (horizontal drain) or 1404.0075 (vertical drain) both have 2 x Ø 40 mm side inelets, which give the option of connecting the washing machine and/or bathtub. The built-in drain trap functions as a central drain trap.
Note! The above outlet units have larger installation heights.
Is it possible to install Unidrain in "soil"? That is, direct connection to the sewage system, which is Ø 110mm?
Yes - For installation in "soil", an outlet unit with the dimension Ø 75 mm is used. Directly on the outlet unit, a reduction/transition is fitted for Ø 110 mm.
Note! Unidrain does not supply outlet units in dimension Ø 110 mm as the above solution gives greater flexibility in the installation.
