Choosing a shower enclosure for a small bathroom
The Abimeister team · Updated · 6 min read
Most Tallinn panel flats have a bathroom somewhere between four and six square metres, and the shower has to share that space with a toilet, a basin, and often a washing machine. The three usual options — a corner enclosure, a single glass walk-in panel, and a shower-bath combination — each solve the space and water problem differently. This guide sets out what actually decides the choice: the measurements that matter, what stops water reaching the rest of the room, and how much upkeep each option asks for.

How much space a shower enclosure actually needs
A corner enclosure needs a genuine 80 by 80 centimetres of floor, and that figure is the inside dimension, not the outer frame. In a panel flat bathroom that is often the only shape that fits, because it tucks into a corner and leaves the rest of the room free for the basin and washing machine.
A walk-in glass panel needs less floor area in one sense — there is no frame or tray lip — but it needs a clear run of wall behind it, usually at least 90 centimetres, for the water to have somewhere to fall without spraying past the glass. In a room narrower than about 1.6 metres this rarely works.
A shower-bath combination takes the most floor space of the three, roughly 70 by 150 centimetres for the bath itself, but it is the only option that also gives you a bath. Where the room is small enough that every centimetre is contested, this is usually the first option ruled out rather than chosen.
Keeping the water in: what actually contains splashes
A corner enclosure with a full glass surround and a proper door seal is the most reliable at keeping water where it belongs, because it encloses the shower on all sides. This matters in a panel flat where the door often opens straight onto a hallway or into a room with a washing machine that should not get wet.
A walk-in panel only shields one side. It works well when the shower head is fixed and aimed away from the opening, but a hand-held shower used carelessly will send water past the glass onto the floor. It suits a household with a settled habit of showering rather than one with children who move around.
A shower-bath combination contains water reasonably well below the rim of the bath, but the curtain or fixed panel above it is the weak point — a poorly hung curtain lets more water out than any glass door. Wherever the enclosure meets a wall, the seal is what actually keeps water inside over months of use, and this is one of the few points where a badly done job shows up as damage rather than just looking untidy; silicone sealing done properly is a small job from 45 € but worth getting right the first time.
Glass thickness and what it means in practice
Shower glass is usually 6 or 8 millimetres of toughened safety glass. The 6 millimetre option is lighter, cheaper, and perfectly adequate for a fixed panel or a door on a well-supported frame — the kind of frame most corner enclosures have.
8 millimetre glass is stiffer and feels more solid underhand, and it is generally what is used for frameless or minimal-frame walk-in panels, because without a full frame around it the glass itself has to resist flexing when someone leans on it or the door swings.
Thickness has little to do with how easy the glass is to clean or how well it resists limescale — that is mostly down to the coating and how often it gets wiped down, not the millimetres. Do not pay extra for thicker glass on a fully framed enclosure where the frame is already doing the structural work.
Sliding or hinged door: which suits a narrow room
A sliding door needs no clearance in front of the enclosure, because the panels run along a track rather than swinging out. In a bathroom where the door to the enclosure faces a basin or a washing machine less than 60 centimetres away, sliding is often the only workable choice.
A hinged door needs room to swing, typically the width of the door itself, and it seals slightly better because there is no track for water and grime to collect in. Where the room allows it — enough clear floor in front of the enclosure — a hinged door is the lower-maintenance option over the years.
Sliding tracks need cleaning more often, since hair and soap residue collect in the channel and the door starts to stick if left. This is a genuine trade-off rather than a matter of preference: measure the clear floor space in front of the enclosure before deciding.
Drain placement and why it is already decided
In most panel flats the floor drain position was fixed when the building was built, and moving it means breaking into the floor slab and altering the fall of the screed towards the drain — a job that goes well beyond fitting an enclosure and usually only makes sense as part of a fuller bathroom renovation.
This means the drain, not the enclosure, is usually what decides where the shower goes and therefore which of the three options fits the room at all. It is worth checking the existing drain position and the direction the floor falls before choosing an enclosure shape, rather than after.
If the renovation is happening anyway — new floor, new fall, new drain position — that is the point at which a corner enclosure, walk-in panel, or shower-bath combination all become genuinely open choices again, not constrained by what is already under the tiles.
Everyday cleaning: which option asks less of you
A corner enclosure with a frame has more corners and channels where limescale and mould collect, particularly along the bottom track and the frame edges. It needs a squeegee pass after each shower and a proper clean with a limescale remover every week or two to stay looking right.
A walk-in glass panel, especially frameless, is the easiest of the three to keep clean day to day — one flat surface, no track, no door seals to work into. The trade-off is the splash containment already covered above.
A shower-bath combination adds the bath itself to the cleaning routine and, if there is a curtain, a piece of fabric or plastic that needs replacing periodically because it cannot be cleaned back to new. Over a few years this is the option that asks for the most sustained upkeep.
- Corner enclosure: needs floor space of at least 80 × 80 cm, contains splashes well, moderate cleaning effort
- Walk-in glass panel: needs a clear wall run of roughly 90 cm behind it, easiest to clean, weaker splash containment
- Shower-bath combination: takes the most floor space, gives you a bath, most cleaning effort over time
- Check the existing floor drain position before choosing a shape, unless the floor is being redone
- 6 mm glass suits a framed enclosure; 8 mm suits a frameless or minimal-frame panel
- Sliding doors suit narrow rooms with little clearance; hinged doors seal better where there is room to swing
Once the decision is made
Once you have settled on a shape, the practical next steps are measuring the actual room — not the flat plan — and checking the drain and any existing waterproofing before ordering glass. A fitted shower enclosure is generally a job from 150 €, and if the bathroom needs more than the enclosure — new floor fall, new tiling, moved pipework — that is a bathroom renovation, generally from 3500 € depending on the scope.
Whichever option you choose, the seals around the enclosure and where it meets the wall and floor are what determine whether the decision holds up over the following years, more than the glass thickness or the door mechanism ever will.
In a small panel-flat bathroom the drain position and the clear floor space usually decide the shape before taste does, so measure both before ordering glass.
