System 3 Zones of Cleanliness — How to Design a Hotel Entrance in 2026
Cleaning, absorbing, and decorative zone. How to choose the width, length, and material to maintain cleanliness of the facility with 1000+ entries per day.
Every commercial property has one common problem: the first 3 meters past the door are a turn-off. 85% of dirt From the outside to the inside. Without an entrance system, this dirt ends up on reception floors, shop floors, and hotel room floors. The result: daily washing tens of times a week, floor replacement once every 3 years instead of once every 10, and an increased risk of slipping on rainy days.
A standard doormat doesn't solve this problem. It solves it project layout of 3 cleanliness zones, where each zone has a different function, length, and material. Below is a complete guide for architects and facility managers planning a new facility or renovating an existing one.
Zone 1 - Exterior (uncovered)
Zone 1 is the area outside the building, usually 0.5–1.5 meters away from the door. Its purpose: to remove the coarsest dirt – mud, snow, pebbles, leaves – before they enter the entryway. Materials must withstand frost, road salt, and intense sunlight.
Recommended Solutions in Zone 1:
- Steel entrance grates — drain water under the grate, easy to maintain, most durable
- Openwork rubber mats — Quick assembly, good for seasonal objects
- Aluminum doormats with brush insert — when zone 1 is roofed
💡 Practical advice
The minimum length of Zone 1 is the length of 2 full steps - i.e., a minimum of 1.2 m. A shorter zone will not have enough time to stop dirt, and the user will pass through it in a single step.
Zone 2 — Vestibule (covered)
Zone 2 is the area under a canopy or in a mudroom. Its function: to clean footwear of residual dirt and begin the drying process. Systemic aluminum mats Combi work here – aluminum profiles with replaceable inserts, chosen according to the type of traffic.
Cartridges available in Zone 2:
- Polypropylene brushes — remove small dirt and sand
- Rubber inserts — drain water, anti-slip (class R10–R12)
- Textile inserts — absorb moisture, premium aesthetics
- Brush + rubber + textiles combination — system Combi, recommended for hotels and galleries
ℹ Long-term ROI
Zone 2 aluminum costs 2–3 times more than a simple rubber mat, but it lasts 10+ years with heavy traffic. You only replace the inserts (every 3–7 years), not the entire system. ROI for a shopping mall: it pays for itself in 18 months on cleaning cost reductions alone.
Zone 3 — Interior of Facility
Zone 3 is the first few meters inside interior doors – in the reception area, lobby hall, and in front of the checkouts. Task: completely dry the soles I absorb the finest dust particles. Here we often design doormats with logos to create the first impression.
Premium materials in zone 3:
- Aluminum profiles + ripstop — best absorption, premium aesthetics
- Protect Excellence Insert (ECONYL®) — from recycling, Cradle to Cradle certified
- Logo mats — milled in rubber, digital printing, textile embroidery
Cartridge Materials — An Overview
Practical length calculation
The total length of all 3 zones should accommodate minimum 5 steps Footwear from the entrance to the clean zone. This is approximately 3.5 m. For high-traffic areas (galleries, 4–5 star hotels), we recommend 4.5–6 m.
Shorter zones act as a symbolic gesture — the doormat is there, but it doesn't stop the dirt. The investor saves PLN 5,000 on a doormat but pays PLN 25,000 annually for cleaning.

Summary — Where to Start a Project
- Measure the distance from the door line to the clean zone (reception, lobby, shops).
- Estimate daily traffic (people per hour) - select system type
- Decide on floor flush-mounting (noseless) or overlay
- Choose the insert material according to the intensity and aesthetics
- Plan maintenance schedule (replacement cartridges every 3–7 years)
Every new project begins with an analysis of the site—traffic, flooring, and climate at the location. A Polentex technical advisor will prepare a free recommendation of 3 zones for your investment.
