Tile flange bath buying guide
A tile flange bath has a raised lip around its rim, and the wall tiles run down over that lip. The bath sits hard against the wall, the tiles finish above the edge, and the join between them is sealed. The baths on this page are all built that way: the Caroma Luna four tile flange bath, the Caroma Vivas anti-slip bath, the Caroma Newbury bath, the Caroma Maxton 1800mm bath and the Decina Bambino inset bath. Four are rectangular and the Bambino is oval. All are white acrylic. Searches for a tiled bathtub, a tiled in bath, a bath flange and a tile flange bath point at the same product, so this is the page to compare them on. Below you will find how the tiling works, what each bath offers, and what to settle before the tiler and plumber arrive.
What a tile flange bath is for
The flange lets the bath go right up against a wall and be tiled over, which gives a water and dust tight seal at the edge. Nothing has to be built around the bath except the support underneath it. The room reads as one tiled surface, and there is no gap behind the rim where dust can settle. That suits a traditional layout, a bath along one wall or in an alcove, and any renovation where the bath should sit quietly into the tiling.
Some of the search terms for this product belong to something else. A tile trim finishes the exposed edge of a tile. A flange is part of the bath and part of how the bath is fitted. If you want a bath, you are in the right place. For the wider family of baths built into a frame or hob, see built in baths.
How the tiling works
On a tiled bath the order of work matters more than anything else. The bath goes on its support first. The membrane follows, rising up the walls behind the bath and lapping onto the flange area. The tiles go on last, over the flange, with the bottom row sitting just above the bath edge. That means the tiler needs the exact flange position before the wall is tiled, so have the bath on site, or its dimensions confirmed, before the wall is finished.
A bath surround is a wet area, and the falls and waterproofing follow AS 3740. The membrane runs under the tiles, over any hob and up the walls, with the junctions detailed so moisture cannot get in. Sanitary silicone belongs at the movement joints, including the line where the tiles meet the bath and the internal corners. Epoxy grout resists staining, so it is the usual pick for splash zones and horizontal surfaces. Cementitious grout suits the walls.
Tile choice around a bath
Porcelain is dense and holds up on horizontal surfaces such as a ledge or hob top, which is where chips and stains show first. Natural stone needs sealing and more upkeep, so it belongs on a feature wall and not in the splash zone beside the taps. Large format tiles leave fewer grout lines to clean. A small mosaic follows curves better but adds joints. Whatever tile you pick, the flange stays the same. It is the tile edge you plan around, not the bath.
Why acrylic baths are fitted this way
Every bath here is sanitary grade acrylic, a light and warm material. An acrylic bath is not tiled over its whole body. Its rim is set at the right height and the tiles stop at the flange. For anyone asking whether tile can go directly on a bathtub, the answer is that tile goes over the flange and only there.
The Caroma Luna four tile flange bath
The Luna has soft, subdued curves that sit comfortably in a contemporary room, from minimalist to family. It comes in 1525mm and 1675mm lengths with a four tile flange, so the tiles can run along every side that meets a wall. The white acrylic has natural slip resistance. Because the bath sits tight to the tiling, nothing collects behind it and cleaning stays easy. The Luna belongs to a wider Caroma range and pairs with matching pieces; Caroma baths shows the full set of shapes and installation types.
The Caroma Vivas anti-slip bath
The Vivas has a plain design and a gently reclining end, so the bather can lean back without sliding down. It comes in 1525mm and 1675mm lengths and has a four tile flange. The anti-slip surface makes it a good call for a family bathroom or a bath that doubles as a shower, and it is one of the baths made to take a shower over them. The flange lets it sit against a wall and be tiled over, which suits a straightforward renovation or a rental where the aim is a clean, durable result.
The Caroma Newbury bath
The Newbury has clean, simple lines and the widest choice of lengths here: 1525mm, 1675mm and 1800mm. An optional headrest or backrest adds support for a longer soak. Its four tile flange is fitted the same way as on the Luna and Vivas, so the decision between the three comes down to length and how much back support you want. The 1800mm size falls in the range that baths over 1700mm covers.
The Caroma Maxton 1800mm bath
The Maxton has a fresh, contemporary shape and integrated armrests. This is the 1800mm length, so with the Newbury 1800 it is the longest bath on the page. The armrests give your hands somewhere to rest and make it easier to shift position, and the four tile flange still holds it tight to the wall. It suits a room with a long wall, where the extra length gives space to stretch out without adding width.
The Decina Bambino inset bath
The Bambino is the oval one, in 1510mm and 1650mm lengths. It is only 380mm deep. Moulded arm rests sweep around from the shoulder, a lumbar support cradles the back, and a slip resistant pattern sits on the base at the entry and exit points. It is made in Australia. Instead of a flange it has a tile bead, which does the same job: the tiles meet the bath at the bead and the join is sealed. Self supporting feet make installation easier, and the waste position is at the end. The shallow depth helps in a small room and for anyone who finds a deep bath hard to step into.
Choosing a length
Most Australian baths are 1500mm to 1700mm long and 700mm to 800mm wide, and every bath here except the 1800mm sizes sits in that band. Start with the wall. Measure the recess between the finished walls and compare it with the bath length, leaving a small gap at each end for sealant. In a tight room the 1510mm Bambino and the 1525mm sizes are the shorter options. 1500mm to 1700mm baths lists that length across every shape and maker, and small baths goes shorter again for a very short wall.
Depth deserves the same attention. A deeper bath holds more water and suits a long soak; a shallow one such as the Bambino is easier to get in and out of. Check the spec sheet for inner depth and fill line before you decide, because they are not always the same figure.
Support under the bath
A full bath is heavy, so the support has to carry the weight evenly. A framed base or a full mortar bed does that properly. Scrap timber, bricks and foam do not hold a bath well once it is full of water and bathers. The Bambino has self supporting feet, which simplifies its base. The Caroma baths rely on the frame the installer builds. Settle the support before the membrane goes on, since everything above it depends on the bath being level and stable.
Waste and plug
The plug and waste are not included with the Caroma Luna, Vivas or Newbury, and the Bambino is sold with its plug and waste separate. Pop-down wastes are the better choice for safety, service and maintenance. Australian building codes require a fully removable bath waste in some situations, so ask your plumber before you order. The waste sits under the bath, which means it should be chosen and fitted before the tiling closes the edge. The bath wastes collection has the options.
A shower over a tile flange bath
A tiled bath is a common base for a shower over the bath, and the Vivas and the Bambino both sit among the baths for that use. For a comfortable shower over a bath, aim for at least 1500mm long and 700mm wide, with a screen to match. The waterproofing runs well up the shower walls and past the bath edges, and it needs its full cure time before tiling. Both baths have slip resistant surfaces for standing in. Shower baths shows the full set.
Care
Rinse the bath after each use and wipe it with a soft sponge or microfibre cloth and a pH neutral cleaner. Keep bleach, ammonia, abrasive powders and steel wool away from the acrylic. On a tiled bath the seals matter as much as the surface, so look at the silicone line along the tiles and at the waste each month, and renew the silicone if it lifts or discolours. Epoxy grout is easier to keep clean than standard grout, and large tiles mean fewer joints to scrub.
Choosing between the five
Start with the room, then the length, then how the bath feels. For a rectangular bath in a standard room, the Luna and Vivas at 1525mm or 1675mm are the practical starting points, and the Vivas adds the reclining end. For a longer soak with a choice of back support, take the Newbury. On a long wall, the Maxton 1800 gives the most length and has armrests. For a small room or easy entry, the Bambino is the shallow oval. Then confirm the waste, plan the tiling around the flange and have the support built before the membrane goes on. The full range of baths is at bathtubs.
