The downstairs bathroom — the design

The design as it stands on 26 September 2026: the materials, fittings and layout, shown at the room’s real size. For the meeting with Mastacon’s interior designer, to check it’s all achievable and to hear her ideas.

All the pictures except the last are AI-enhanced images, not photographs. They start from a 3D model built to the measured working drawings (rev H), then an image model added surface texture, lighting and a little styling — the bottles, vase and plant. Treat the colours as indicative: the real Capital Pearl tile is paler than the first set shows. The last picture is the model itself, and is the one to trust for proportions. In the first set the mirror reflection bends and there are tan patches at the foot of the third picture; both are faults in the model, fixed in the variant.

The current design (pictures 4–6) adds three things to the first set: an organic walnut mirror, 90 × 82, in place of the round oak one (drawn backlit; the backlight was dropped on 30 Oct 2026); a hidden LED in a narrow ceiling slot against the fluted wall, washing light down the ribs; and a round basin with a rugged chiselled-stone exterior in place of the white oval. The basin was drawn by the image model from a reference photo, so its exact shape is indicative. All three are on the list below.

Room: 2861 × 1909, ceiling 2730 (measured, 10c). Walk-in shower 1009 wide behind an 810 half-height wall (about 1100 high).

Feature walls: AMS Surfaces Capital Pearl Concave, CP12601NDD5, 600 × 1200 porcelain, flutes vertical — on the wall behind the vanity and shower head, and on the shower’s window wall. All other walls: AMS Capital Pearl natural, CP12601ND, 600 × 1200, laid vertically. AMS Surfaces, 59 Grange Rd Welland, 08 8352 1265. Showroom prices $88 and $50.60 (unit and GST to confirm).

Floor: Castelvetro Life Bianco 600 × 600 porcelain — natural CLE60R1, or the textured grip version CLE60R1S in the shower. Supplier to confirm (seen on the 25 Sep showroom visits). Laid with a planned layout — every tile differs.

Benchtop and shelf top: Taj Mahal quartzite, honed, 20 mm, from AMS. Alternatives being weighed: Zenith Dubai Drift, Kaya Sienna, Caesarstone ICON 4001 Fresh Concrete and 4011 Cloudburst Concrete.

Vanity: custom floating, 1760 long, 500 deep, four drawers, Laminex AbsoluteGrain Classic Oak, recessed shadow-line finger pulls, LED strip underneath. Basin: in the first set, an oval white vessel; now the stone vessel or a matte black undermount (being priced). Mirror: walnut, framed, not backlit; we supply it and Mastacon installs (still for discussion).

Fittings: all matte black (PVD being priced) — wall-mounted basin mixer and spout, rain head with a hand shower on a rail, linear floor drain, heated towel ladder on a timer. No chrome, brass or gold anywhere.

Glass: 12 mm toughened, frameless, in channels recessed into the half wall and back wall so no metal shows; 150 mm radius on the free top corner.

Window: AAW 600 × 1510, head 2400, sill about 1800, frosted glass, matte black frame. Shelf: the drawn ledge at 1200, full length.

Services: 3000K downlights, one over the shower shelf; under-vanity LED on a motion sensor as a night light; humidity-sensing exhaust fan with run-on.

To confirm or price

Is it all achievable as drawn and specified here, within a normal tiling and joinery allowance? Anything she would change?
Her ideas — this is a short-stay rental and the aim is a “wow” bathroom that is still quick to clean between guests.
Fluted tile: stock and lead time for three dwellings from one batch; how she details the external corners and where the flutes meet the flat tile.
Fittings on the flutes: a flat patch or a flat tile behind the shower mixer, rail and basin taps?
Frameless glass in recessed channels with no bar, 150 mm radius corner — has she done it on a half wall this size?
Shower ledge topped in an offcut of the benchtop stone, falling back into the shower.
Vanity: custom floating joinery with the recessed shadow-line finger pull — who makes it, and does the Laminex oak wrap into the reveal?
Paint: the only painted surfaces are the ceiling and the door. Her pick of warm white against the Pearl tile.
Lit fluted wall: a linear LED in a narrow slot in the ceiling, tight against the fluted wall behind the vanity and shower, washing straight down it so every rib throws a shadow. It has to be framed into the ceiling before sheeting. Is she happy with the detail? Which LED and driver, and where is the dimmer?
Basin: a round vessel with a rugged, chiselled stone exterior and a smooth bowl (chosen 28 Sep; reopened 4 Nov: John now leans to a matte black undermount basin, and Mastacon is pricing both), in place of the plain white oval — stone-beige to match the tile and top. Natural stone or a sealed concrete version of the same form (e.g. Sticks & Stone Co Round Rugged, Ø400, ~$740)? Concrete is favoured for a rental: natural stone stains from toothpaste, dye and fake tan. No overflow, so an unslotted waste; nine across the three dwellings, one colour batch. Pictures 4–6 show the stone basin.
Mirror option: instead of the round backlit mirror, an organic-shaped solid timber mirror (Etsy maker; 90 × 82 for the two downstairs vanities, 75 × 68 for the ensuite — nine across the three dwellings; walnut or oak). John has the 90 × 82 in walnut in his own ensuite. It isn’t backlit as sold, and it’s heavy: noggings in the wall behind it before tiling. Decided at the lighting meeting, 30 Oct 2026: no backlight, so no LED strip and no power behind it. The contract's nine round backlit LED mirrors (item 32) are therefore not wanted: please credit them, or credit the difference if Mastacon supplies and hangs a plain round mirror instead.
