# Bathroom Renovation
|
||
|
||
> **Started:** 2026-03-07
|
||
> **Status:** Planning
|
||
|
||
---
|
||
|
||
## Current State
|
||
|
||
Describe what the bathroom looks like now: dimensions, fixtures, materials, condition.
|
||
|
||
- **Dimensions:** L-shaped, see blueprint. Long edge (F) 2600mm, top (A) 2500mm, bottom (E) 1500mm, nook 1000x1000mm
|
||
- **Ceiling height:** 2400mm
|
||
- **Current flooring:** _TODO_
|
||
- **Current wall finish:** _TODO_
|
||
- **Fixtures:**
|
||
- Sink/vanity: 550x350mm on wall F, 50mm from wall E (between bath and door)
|
||
- Shower: ~1000x1000 nook (top-right corner), water point middle of wall B
|
||
- Bathtub (current): 1850x850, upper-left corner along wall F, water point middle of bath on wall F
|
||
- Bathtub (planned): freestanding corner bath ~1800x800 (no brick surround)
|
||
- Mirror: large mirror with diffuse ring light (keeping)
|
||
- Shelf: wall A, 800mm long, 250mm deep, 500mm from wall F — want to keep something similar here (visual break, not necessarily storage)
|
||
- Shower mirror: ~300mm small mirror in the shower for shaving — want to keep this in the future bathroom. Suction cup mount is probably best (removable, no drilling). See [bol.com scheerspiegels](https://www.bol.com/nl/nl/l/scheerspiegels/22845/)
|
||
- Sink-side storage: two [IKEA TISKEN suction cup baskets](https://www.ikea.com/nl/nl/p/tisken-mand-met-zuignap-zwart-90498528/) on wall F next to sink — functional but need a nicer replacement
|
||
- **Plumbing location:** shower water on wall B, bath water on wall F
|
||
- **Ventilation:** vent on wall D, 200mm wide, 750mm from wall E (no window). Connected to whole-house mechanical ventilation — single motor just behind the opening. Currently always open, causing heat loss.
|
||
- **Electrical:**
|
||
- Ceiling: [Philips Hue Devere](https://www.philips-hue.com/nl-nl/p/hue-white-ambiance-devere-grote-plafondlamp/4116631P6#specifications) — 420mm, 1100mm from wall F, 700mm from wall A (keeping)
|
||
- Mirror: [Philips Hue Adore](https://www.philips-hue.com/nl-nl/p/hue-white-ambiance-adore-badkamerspiegel-met-verlichting/8719514340992) — 560mm wide, 60mm from wall E, above sink (keeping)
|
||
- **Heating:** towel rail radiator on wall D, 600mm wide, 600mm from door — needs replacing. Tado smart heating system with pre-heat scheduling.
|
||

|
||
|
||
## Goals / Requirements
|
||
|
||
What should the new bathroom achieve?
|
||
|
||
- [x] Keep the bathtub — replacing with a freestanding corner bath (~1800x800, no brick surround)
|
||
- [x] Keep the shower in the existing nook
|
||
- [x] No toilet (no room, not needed)
|
||
- [ ] _TODO — style/aesthetic direction_

## Things to Think About
|
||
|
||
### Ventilation — Upgrade the Vent Grille
|
||
- The bathroom connects to a whole-house mechanical ventilation system (single motor behind the vent opening on wall D). There is no separate bathroom fan — the central system provides extraction.
|
||
- **Problem:** The vent is always open, which means continuous heat loss and unnecessary suction when the bathroom is dry. The motor runs regardless.
|
||
- **Solution: humidity-sensitive vent grille.** These exist and work without electricity — a polyamide strip inside the grille expands/contracts with moisture, mechanically opening/closing the shutter. When humidity rises (shower, bath), the grille opens fully. When the room is dry, it closes to a minimum, reducing heat loss and balancing airflow across the house.
|
||
- **Options:**
|
||
- **[Aereco EHT²](https://www.aereco.com/products/air-inlets/eht2/)** — wall-mounted humidity-sensitive inlet, fully mechanical (no power), up to 52 dB acoustic insulation. Designed for exactly this use case: existing mechanical ventilation with passive grille replacement. This is the most directly applicable product.
|
||
- **[Aereco humidity-sensitive exhaust grilles](https://www.aereco.com/product-control/humidity-sensitive/)** — if the vent is on the extraction side (which it is), Aereco also makes extraction-side grilles that modulate airflow based on room humidity.
|
||
- **Electronic alternative:** A humidity sensor switch (e.g. Topgreener TDHS5, Lutron Maestro MS-HS3) could control a motorised damper, but this adds wiring complexity. The passive Aereco approach is simpler for a central system.
|
||
- **During renovation:** This is the ideal time to swap the grille. The duct behind it is already there. Just measure the duct diameter/opening size and match an Aereco or equivalent product to it.
|
||
|
||
### Lighting
|
||
- Both lights are Philips Hue White Ambiance — tuneable colour temperature (2200-6500K) and dimmable via the Hue app or automation. No hardware dimmer needed.
|
||
- The Devere (IP44) covers ambient, the Adore handles task lighting at the mirror. That covers all essential layers.
|
||
- If adding anything, a small accent (LED strip in a shower niche) is the only gap. Not essential.
|
||
|
||
### Waterproofing — Do Not Cut Corners
|
||
- The entire shower area and bath surround must be tanked (liquid membrane or sheet membrane) before tiling. This is non-negotiable.
|
||
- Extend waterproofing at least 150mm beyond the shower/bath edges. Many professionals recommend tanking the full wet wall floor-to-ceiling.
|
||
- The floor should be fully waterproofed, especially at the bath and shower zones.
|
||
- Use flexible waterproof tape on all inside corners and pipe penetrations.
|
||
- Get this inspected before tiling — you cannot fix it later without ripping tiles off.
|
||
|
||
### The L-Shape: Use It
|
||
- The nook (1000x1000) is a natural shower enclosure. A single glass panel or frameless screen is all you need — the walls do the rest.
|
||
- The L-shape creates a natural separation between wet zone (shower/bath side) and dry zone (sink/door side). Lean into that.
|
||
- Consider where the towel rail goes — the wall between the sink and the door (wall E, 550mm segment) or the inside of wall D above the radiator.
|
||
|
||
### Style Directions Worth Exploring
|
||
- **Warm spa:** matte stone-look porcelain, oak or walnut vanity, brushed nickel, soft mirror lighting, muted green or clay accents.
|
||
- **Quiet hotel:** seamless tile palette, floating vanity, frameless shower glass, minimal grout contrast, concealed storage.
|
||
- **Vintage modern:** characterful floor tile, more furniture-like vanity, framed mirror, decorative sconces, warmer metal finishes.
|
||
|
||
### Plumbing: Keep It Where It Is
|
||
- Moving drain lines is expensive and disruptive (especially in concrete floors). If the current drain positions work, keep them.
|
||
- Moving supply lines (hot/cold) is much cheaper than moving drains. Adjusting tap positions on the same wall is usually straightforward.
|
||
- If replacing the bath, confirm the new one fits the same drain position or plan a short drain extension.
|
||
|
||
### Heated Floor — Probably Not
|
||
- At 2400mm ceiling height, adding underfloor heating raises the floor ~15-20mm (mat + adhesive + tile build-up vs direct tile). That eats into an already low ceiling.
|
||
- With Tado you can pre-heat the room via the towel radiator on a schedule, which largely solves the cold-floor-in-the-morning problem.
|
||
- A good towel rail radiator replacement gives you warm towels and room heating in one. Prioritise that over underfloor heating.
|
||
- If you still want warm feet, a small electric bath mat is a zero-build-up alternative.
|
||
|
||
### Tile Choices
|
||
- Large format tiles (600x600 or larger) with thin grout lines make a small room feel bigger. Fewer grout lines also means less cleaning.
|
||
- Light colours reflect light and help compensate for the lack of a window. Dark feature walls can work but keep them to one wall max.
|
||
- Consider the same tile on floor and walls (or floor and lower walls) for a seamless look that visually expands the space.
|
||
- Non-slip rating matters, especially for the shower floor. Look for R10 or R11 rated tiles in the wet zone.
|
||
|
||
### Storage
|
||
- In a small bathroom, surface clutter kills the feel fast. Plan recessed niches in the shower wall during the build — much cheaper than retrofitting and they do not eat floor space.
|
||
- A mirrored cabinet above the sink gives storage and a mirror in one.
|
||
- If the vanity is wall-mounted (floating), the visible floor underneath makes the room feel larger.
|
||
- **Wall A shelf (existing: 800x250mm, 500mm from wall F):** The current shelf breaks up the long wall nicely. Consider replacing with a similar floating shelf in a material that matches the new design (e.g. solid oak, stone-look composite, or a tiled niche built into the wall). It does not need to be deep — 150–250mm is enough for candles, a plant, or decorative objects.
|
||
- **Sink-side storage (replacing TISKEN baskets):** Options that look better than suction cup baskets:
|
||
- Wall-mounted wire or metal basket shelf (e.g. matte black steel) — screwed in, not suction
|
||
- Small floating shelf or pair of shelves next to the mirror
|
||
- If the vanity has drawers, move most items inside and keep the wall clean
|
||
- A recessed niche in wall F next to the sink (decide during tiling phase — cannot add later)
|
||
|
||
### Light Switch: Need a Physical Switch with Smart Control
|
||
- The Hue lights are smart-controlled, but a physical wall switch is still needed (guests, muscle memory, building codes in some areas).
|
||
- If someone flips a dumb switch and cuts power, the Hue bulbs go offline. A smart switch solves this.
|
||
- **Options compatible with Philips Hue:**
|
||
- **Philips Hue Wall Switch Module** — installs behind your existing switch plate. The physical switch stays but toggles a Hue scene instead of cutting power. Easiest drop-in solution. ~€40.
|
||
- **RunLessWire Click for Philips Hue** — wireless, battery-free (kinetic energy). Pairs natively with the Hue Bridge. Can be placed anywhere, no wiring. ~€35–50.
|
||
- **Friends of Hue switches (Senic / Gira)** — built-in wall switches using Zigbee Green Power (no battery). Premium look, proper wall-plate form factor. Pair directly with Hue Bridge. €50–100+ depending on brand/finish.
|
||
- **Inovelli Blue Series** — Zigbee 3.0 in-wall switch with built-in humidity sensor (useful for a windowless bathroom). Does **not** pair directly with Hue Bridge; requires SmartThings or Home Assistant as a bridge. More complex but more capable. ~$50.
|
||
- **Recommendation:** The Hue Wall Switch Module is the simplest if you already have a switch plate. If you want a clean wireless option with no wiring at all, the RunLessWire Click is worth considering.
|
||
|
||
### Radiator Replacement
|
||
- The existing towel rail radiator on wall D needs replacing. Same position works (vent is above it, plumbing connections are there).
|
||
- Size the replacement to the available space: 550mm wide fits the wall, 600mm gap to door below, vent at 750mm from wall E.
|
||
- With Tado controlling the schedule, the radiator does double duty: room pre-heating and towel warming.
|
||
- **Options (matte black, central heating):**
|
||
- **[Kepler](https://www.maxaro.nl/radiatoren/handdoekradiatoren/kepler-handdoekradiator-55x174-cm-mat-zwart-1242-watt-aluminium-centrale-verwarming-7056/)** — 550x1740mm, 1242W, aluminium. Tall and powerful. At 1740mm height it would start ~600mm from floor (above door gap) and reach ~2340mm — just under the 2400mm ceiling. Leaves ~60mm clearance. Tight but doable.
|
||
- **[Oberon](https://www.maxaro.nl/radiatoren/handdoekradiatoren/oberon-handdoekradiator-55x130-cm-mat-zwart-471-watt-staal-centrale-verwarming-176373/)** — 550x1300mm, 471W, steel. More compact, fits comfortably in the space (600mm + 1300mm = 1900mm, well under ceiling). Lower output — check if 471W is sufficient for the room volume (~11.8 m³).
|
||
- **Fit note:** Both are 550mm wide (current radiator is 600mm). The vent is at 750mm from wall E — the Kepler would overlap vertically with the vent position. Confirm whether the vent can sit above the radiator or if there needs to be clearance between them.
|
||
|
||
### Common Mistakes to Avoid
|
||
- Not budgeting for contingency (15% minimum). There are always surprises behind old tiles.
|
||
- Choosing fixtures before confirming they physically fit. Measure clearances: 200mm minimum from sink centre to side wall, 600mm clear in front of any fixture.
|
||
- Forgetting about the door swing — yours opens outward (good), so no conflict, but check nothing blocks it from the corridor side.
|
||
- Skipping a site visit with your plumber before demolition. Let them see the existing setup and flag issues.
|
||
- Over-specifying trendy finishes that date quickly. Neutral base, personality through accessories.
|
||
|
||
### If I Were Optimizing This Layout
|
||
- Keep the shower in the existing nook unless plumbing constraints make it painful. That part of the plan is already doing useful work.
|
||
- Use a wall-hung vanity with drawers rather than a freestanding cabinet. In a room this size, visible floor area helps.
|
||
- Make the freestanding bath feel deliberate: consider a ledge or niche nearby, proper bath filler position, and enough surrounding calm that it reads as an asset rather than leftover compromise.
|
||
- Reduce the number of finish changes. A smaller room usually benefits from calm surfaces more than from visual variety.
