Kartell K-VIT Atlantis Waterproof Bathroom Furniture: The Complete 2026 Guide

Here's an uncomfortable truth about most bathroom furniture: it lives in the wettest room in the house, yet it's usually made from boards that merely tolerate moisture. Give it a few years of steamy showers, splashy kids and mopped floors, and the tell-tale signs appear — swollen edges, lifting veneer, that soft spongy feel at the plinth. Kartell K-VIT's Atlantis range takes a different approach: fully waterproof construction throughout. Not moisture-resistant. Waterproof. In this guide we walk through the entire 2026 range — vanity units, space-saving L-shaped furniture packs, WC and tall units, and waterproof bath panels — all in stock at Essential Bathrooms at 45% off RRP with fast UK delivery.

Waterproof vs moisture-resistant: why it matters

Standard bathroom cabinets are typically made from moisture-resistant MFC or MDF — fine in a dry, well-ventilated room, but vulnerable where water actually gets to work: plinths sitting on damp floors, panel edges, the cabinet under a leaky trap. Atlantis cabinets are engineered to be fully waterproof, so they will not swell, warp or peel — even in a busy family bathroom that never quite dries out. If your bathroom works hard, this is the difference between furniture that lasts three years and furniture that lasts fifteen.

The vanity units: 500mm and 600mm

The core of the range is a pair of floor standing 2 door vanity units in bright white gloss, each supplied complete with a white ceramic basin:

• The Atlantis 500mm Vanity Unit & Basin (ATL500VU) — £225.50 (was £410). With a slimline 380mm depth, it's the pick for en-suites and compact bathrooms.
• The Atlantis 600mm Vanity Unit & Basin (ATL600VU) — £237.05 (was £431). A roomier basin and bigger cupboard for just £11.55 more — the family bathroom workhorse.

Both have soft-close doors, generous concealed storage and that fully waterproof carcass. Browse them alongside the rest of our floor standing vanity units.

The stars of the range: 1100mm L-shaped furniture packs

New for 2026, the L-shaped packs squeeze a complete bathroom furniture run — vanity, basin and concealed WC — into just 1100mm of wall space. The 600mm L-shape vanity unit sits beside the 500mm L-shape WC unit, and an L-shaped ceramic basin spans across the top to create one seamless worktop line. Even better, the concealed cistern is included — just add your choice of back-to-wall pan.

They're handed, and choosing is simple: stand facing the unit. If you want the basin on the left, order the Left Hand pack; basin on the right, order the Right Hand pack. Both are £421.58 (was £766.50) — and with the cistern included, the value is hard to beat for a full furniture run.

The WC unit: conceal the cistern in 247mm

Prefer to build your own run? The Atlantis 500mm WC Unit (ATL500WC) — £103.95 (was £189) — hides the cistern and pipework behind a slim 247mm-deep waterproof cabinet, with a worktop that doubles as a handy shelf. It sits flush alongside either vanity unit for a continuous furniture line. (Cistern and back-to-wall pan are sold separately with this standalone unit.)

The tall unit: storage that climbs the wall

The Atlantis 1200mm Wall Mounted Tall Unit (ATL1200TU) — £167.75 (was £305) — is the storage multiplier. At 1200mm tall but only 300mm wide and 231mm deep, it tucks beside the basin or shower and swallows towels, toiletries and cleaning kit, while wall mounting keeps the floor clear for easy cleaning. See it with our other wall mounted tall storage units.

Waterproof bath panels: five sizes

The same thinking extends to the bath. Standard bath panels often degrade exactly where they meet the floor — the wettest spot in the room — but Atlantis panels are fully waterproof throughout, so they keep their crisp white gloss looks for years:

• Front panels: 1600mm and 1700mm at £78.10, and 1800mm at £83.60
• End panels: 700mm at £33.00 and 800mm at £44.55

Pick the front panel to match your bath length and add an end panel if the end of your bath is exposed. Browse the full bath panel collection for more options.

Three ways to build an Atlantis bathroom

The compact en-suite: the 500mm Vanity Unit with the 1200mm Tall Unit alongside — a full storage solution in under a metre of floor space.

The family bathroom: the 600mm Vanity Unit plus the 500mm WC Unit for a continuous run, with 1700mm front and 700mm end panels finishing the bath to match.

The all-in-one: an 1100mm L-shaped furniture pack — vanity, basin, WC unit and cistern in one order, one delivery, one seamless line.

Frequently asked questions

What does "fully waterproof" actually mean?

Most bathroom furniture uses moisture-resistant board, which tolerates humidity but can swell or warp with sustained water contact. Atlantis cabinets are fully waterproof throughout, so they will not swell, warp or peel — even with direct, repeated exposure to water.

What's included in the 1100mm L-shaped furniture packs?

The 600mm L-shape vanity unit, the 500mm L-shape WC unit, the L-shaped ceramic basin and the concealed cistern. The back-to-wall toilet pan, brassware and waste are sold separately.

How do I know if I need a left hand or right hand pack?

Stand facing where the unit will be installed. If the basin should be on your left, choose the left hand pack; on your right, the right hand pack. If you're unsure, email sales@essentialbathrooms.co.uk before ordering and we'll happily confirm.

Does the standalone WC unit include the cistern and pan?

No — the standalone ATL500WC houses a standard concealed cistern and back-to-wall pan, which are sold separately. The L-shaped furniture packs do include the concealed cistern.

What size baths do the Atlantis panels fit?

Front panels come in 1600mm, 1700mm and 1800mm lengths to suit standard baths, with 700mm and 800mm end panels for exposed bath ends.

What guarantee does Atlantis furniture carry?

All Atlantis products from Essential Bathrooms are genuine Kartell K-VIT, backed by a 5-year guarantee.
