Open year-round.
5-star reviews.
One odour complaint, remembered forever.

Irish hotels operate twelve months a year — but occupancy doesn't. Mid-week rooms sit empty for days. Off-peak floors get rotated out of service. Every unused P-trap dries out. The next guest checks in, opens the bathroom door, and smells sewage. That TripAdvisor review lasts forever. Green Drain solves it in 30 seconds per trap.

Problem & solution

Variable occupancy is a structural risk for Irish hospitality

From Dublin city-centre business hotels to Wild Atlantic Way resorts and Lakelands country properties — Irish hotels stay open year-round, but rooms cycle in and out of use constantly. Corporate travel slows after autumn. Mid-week occupancy drops in shoulder season. Floors rotate out of service for maintenance. Every empty room means a P-trap evaporating dry — and the first guest to walk in after smells the sewer.

Without Green Drain™

  • P-traps in low-use rooms evaporate within 3–7 days — bathroom drains, shower wastes, floor gullies.
  • Sewage gases (H₂S, NH₃) pass through the dry trap — "that smell" the moment the guest opens the door.
  • TripAdvisor reviews with the words 'drain', 'sewage', 'smell' — permanent SEO damage.
  • Housekeeping manually runs water through every trap in unoccupied rooms — extra workload, often skipped.
  • Fruit flies in F&B blocks — a sanitary risk for HACCP.

With Green Drain™

  • No priming needed — the silicone skirt seals dry traps automatically, even after weeks of vacancy.
  • No sewer odours in any area with drains — rooms, corridors, F&B, back-of-house.
  • HACCP approved for the F&B subzone — covers kitchen, prep areas and guest zones.
  • No chemicals, no glycol-based trap primers — eco-conscious properties and B Corp hotels appreciate it.
  • Quiet operation — guests never hear backflow when someone upstairs flushes.

Model Recommendation

Recommendation per zone at the hotel

Irish hotel construction: 3-star and 4-star properties typically have DN50 in rooms (GD 2), while 5-star and premium boutique hotels often have DN65 (GD 2.5) for deeper P-traps. Food & beverage, wellness, and technical areas use larger sizes. Hotel complexes with self-catering lodges and apartments need a mix of specifications.

Green Drain™ Recommended for your industry.

  • 3-star and 4-star rooms (the largest share of Irish hotel stock)GD 2. Standard DN50 seal.
  • 5-star rooms and premium boutique hotelsGD 2.5. Deeper P-traps in luxury construction.
  • Wellness centre — shower cabins and hammamGD 3 or GD 3.5. Chlorine, intensive cleaning.
  • F&B kitchens and stewardingGD 3 (line) + GD 4 or GD 5 (central gullies).

Questions

Most common doubts

How long does one installation last?

Five years under normal use. Visual inspection once a year as part of standard PPM — no scheduled removal, no replacement during the lifespan.

What about glamping cabins and self-catering lodges?

Ideal use case. Glamping pods, lodges and self-catering units use standard 2″ P-traps — the GD 2 fits, stays in place, and protects through every changeover gap, no matter how long the unit sits empty between guests.

And short-term rentals (Airbnb, Booking, serviced apartments)?

Absolutely. Short-let units that sit empty between bookings have the exact same dry-trap problem. Hosts using Booking.com, Airbnb and Sykes Cottages appreciate the absence of "smelly bathroom" reviews — the single most damaging review type for hospitality SEO.
