An in-house hotel laundry needs three equipment stations sized around one number: your daily linen load in kilograms. Washer-extractors come in standard capacities from 15-120 kg (larger available on request), and everything downstream (dryers, ironer, folder) is sized to keep pace with whatever the washers put out. As a starting point: 100-200 room hotels typically run 2-3 washer-extractors in the 30-50 kg class with matching dryers and a compact 1-3 roll flatwork ironer. 300-500 room properties move into 100 kg-class machines, add a 5-roll ironer line, and usually reach the volume where a dedicated pillowcase ironing line pays for its own floor space. 600-1,000 room properties need multiple large-capacity washer-extractors, a high-speed thick-drum ironer with feeder, and a fully separated pillowcase line running alongside the main flatwork line. This guide uses real capacity and dimension data for HOZO Laundry, an industrial laundry equipment manufacturer, as a working reference; the sizing logic below applies no matter which supplier a hotel ultimately chooses.

How Much Laundry Does a Hotel Actually Produce?
Linen generation is usually estimated in kilograms per occupied room per day. The industry-wide range commonly used for planning is roughly 5-8 kg/occupied room/day: the low end fits limited-service properties with lighter bedding and fewer terry items, the high end full-service and resort hotels with heavier duvets, bathrobes, and multiple towel changes.
Because equipment has to handle your busiest days, not your average ones, size for design occupancy (typically 85-90%) rather than actual average occupancy. The formula:
Daily linen load (kg) = Rooms × Design occupancy (%) × kg per occupied room/day
A 300-room hotel at 85% design occupancy and a mid-range 6.5 kg/room/day generates roughly 1,650 kg of linen a day. That single number drives every equipment decision below.
Once you have a daily kg figure, machine count follows one more formula, applied to each equipment category:
Machines needed = Daily load ÷ (Machine capacity × Cycles per shift × Shifts per day)
A commercial washer-extractor typically completes around 8 full wash-rinse-extract cycles in an 8-hour shift, assuming a standard 45-55 minute hotel linen program including load/unload time. Heavily soiled loads or extra rinse steps bring that number down. Most single-property in-house laundries run one shift; higher-volume operations add a second.
Configuration by Room Count: Quick Reference
| Room count | Daily linen load | Washer-extractors | Dryers | Ironer / finishing | Pillowcase line |
|---|---|---|---|---|---|
| 100-200 rooms | ~550-1,100 kg/day | 2-3 × 30-50 kg (XGQ-30F/50F) | 2-3 × matching capacity (HG-30/50) | Compact 1-3 roll Y series, 3300mm | Optional; often shares the main ironer at this volume |
| 300-500 rooms | ~1,650-2,750 kg/day | 3-4 × 100 kg (XGQ-100F) | 3-4 × 100 kg (HG-100 or HSG-100) | 5-roll Y series line, 130-150 pcs/h | Usually justified: HPT-1400, 1,500 pcs/h |
| 600-1,000 rooms | ~3,300-5,500 kg/day | 4-7 × 100-120 kg (SXT-100FQ/120FQ) | 4-7 × HSG-100 | 6-roll YH thick-drum, 200-250 pcs/h + feeder | Dedicated line: HPT-1400-S, 1,800 pcs/h |
These are starting points, not fixed rules. Every property’s linen mix, shift pattern, and turnaround expectations shift the exact count. Treat the ranges below as a planning baseline to bring to your equipment supplier.
100-200 Rooms: Boutique and Full-Service Hotels
At 100-200 rooms, daily linen runs roughly 550-1,100 kg. Applying the machine-count formula against a 30-50 kg (XGQ-30F/50F) washer-extractor running 8 cycles on a single 8-hour shift (240-400 kg/machine/day), most properties in this tier need 2 machines to cover the lower half of the range and 3 machines (or a partial second shift) toward 180-200 rooms. See the industrial washing machine range for the full capacity table.
Dryers are matched to washer batch size, generally 1:1. An HG-30/50 pairs cleanly here. HOZO’s HG series uses a larger drum volume that produces a fluffier finish, which matters at this scale because boutique and full-service properties tend to weight amenity quality (towel feel, bathrobe softness) over raw throughput.
Flatwork volume (sheets, duvet covers, table linen) is modest relative to towels and pillowcases at this room count, so a compact 1-3 roll Y series ironer (3300mm working width, 3-25 m/min conveying speed depending on roll count) is normally enough to keep pace without idle capacity. Pillowcases can usually still run through this same ironer at this volume; the efficiency case for a separate line strengthens as room count grows (see below).
300-500 Rooms: Mid-Size and Convention Hotels
This tier’s daily linen load, roughly 1,650-2,750 kg, is where equipment class typically steps up from the 30-50 kg range to 100 kg (XGQ-100F). At 8 cycles/shift, a 100 kg machine processes about 800 kg/day, so the tier needs 3 machines at the low end and 4 machines (or extended shift hours) toward 500 rooms.
Dryer selection becomes a real choice at this scale between HG-100 and HSG-100. Both handle 100 kg-class batches, but HSG’s forward-flow steam design and variable-speed fan complete a 100 kg batch in about 45 minutes at lower steam consumption than HG-100 processing a comparable load. That trade is worth weighing if steam cost or throughput speed matters more than the extra fluffiness HG’s larger drum gives towels. Neither is simply “the faster version” of the other; they’re positioned for different priorities.
At 1,650+ kg/day, flatwork volume justifies a 5-roll Y series ironer (130-150 pieces/hour) with a feeder ahead of it rather than manual spreading. This is also the volume range where a dedicated pillowcase ironing line (HPT-1400, 1,500 pieces/hour) starts paying for its own floor space (see the differentiation note below).
600-1,000 Rooms: Large Resorts and Convention Properties
Daily linen at this scale runs ~3,300-5,500 kg, well beyond what standard 100 kg machines can clear on a single shift without an unrealistic machine count. This is where SXT-100FQ/120FQ tilting washer-extractors (100-120 kg, 18° tilt with 180° door opening for faster reload) fit the “high-frequency, high-intensity” profile these properties run. At roughly 880 kg/machine/day (8 cycles, ~110 kg average), the tier needs 4 machines at the low end and up to 7 machines near 1,000 rooms. Most operations at this volume split the load across 1.5-2 shifts rather than running the full machine count on one shift, which also helps flatten peak steam and electrical demand.
Dryers pair 1:1 with washers; HSG-100 is the practical default here purely on steam economy at this scale (100 kg per 45-minute batch vs. HG-100’s 60 kg in the same time, at meaningfully lower steam draw). HG remains the right call in any zone still prioritizing towel fluffiness (spa, premium bath amenity).
Flatwork at this volume calls for the 6-roll YH thick-drum ironer (200-250 pieces/hour). The thicker heating drum (10-12mm vs. the standard 4mm) holds heat under continuous high-speed operation instead of cooling as wet linen passes through, which keeps ironing quality consistent at speed. A single operator hand-feeding can’t keep pace with a 6-roll YH line, so a feeder or spreader ahead of it is standard at this tier, not optional. See the flatwork ironer category for the full roll-count range. Large-scale properties running heavy towel volume alongside this also typically add a separate towel-folding step downstream of the dryer, a different machine and workflow from flatwork folding, since towels aren’t ironed.
At this room count, a dedicated pillowcase line (HPT-1400-S, 1,800 pieces/hour) moves from “usually justified” at 300-500 rooms to close to essential.
Why Pillowcases Deserve Their Own Line
Here’s the detail that’s easy to miss when scaling up an equipment list: a standard flatwork ironer runs 3300mm wide, but a pillowcase is roughly 600mm. Running pillowcases through the main ironer means only about a fifth of that width is doing useful work. The rest of the heated roller runs hot against nothing, burning steam for no output. At 300+ rooms, with two pillows turned over per room per stay, that’s a meaningful volume of small, uniform items competing for the same machine as your sheets and duvet covers.
A dedicated 1400mm pillowcase line (HPT-1400 / HPT-1400-S) built around a smaller-diameter roller sized specifically for pillowcase width does two things at once: it clears pillowcases faster (1,500-1,800 pieces/hour vs. sharing time on the wide ironer) and it frees the main flatwork line’s full width and speed for the large-format items it’s actually sized for. We go deeper on the mechanics and payback logic in our dedicated pillowcase ironing line guide.
Common Configuration Mistakes
- Sizing washers for average occupancy instead of design occupancy. A laundry sized for 65% average occupancy backs up badly on the property’s busiest nights. Size for the peak, not the mean.
- Undersizing the dryer relative to washer batch weight. If the dryer’s per-cycle capacity is smaller than what the washers are loading per cycle, the dryer becomes the bottleneck regardless of how many washers you have.
- Treating HSG as “just a faster HG.” They’re built for different priorities: drum size and finish (HG) vs. steam efficiency and cycle speed (HSG). It’s not a straight speed upgrade of the same machine.
- Running pillowcases through the main flatwork ironer past ~300 rooms. It works, but it wastes width and steam that a dedicated 1400mm line uses efficiently (see above).
- Planning only for machine footprint, not workflow space. Equipment dimensions alone understate the room you need; sorting, staging, loading/unloading clearance, and linen storage typically add well beyond the machines’ raw footprint (see floor area estimates below).
- Mixing up capacity units when comparing machines. Washers and dryers are rated in kg per load; ironers and pillowcase lines are rated in pieces per hour or line speed in m/min. Adding these together or assuming they scale the same way leads to mis-sized lines.
Floor Area: A Rough Planning Starting Point
Machine footprint alone doesn’t tell you how big to build the room. You also need clearance for loading, unloading, sorting carts, and staff movement. A commonly used industrial engineering rule of thumb is 2-2.5× the combined machine footprint for the working floor area, before adding separate space for soiled/clean sorting, linen storage, and staff facilities.
Using the equipment mix described above as an illustration (not a substitute for a layout drawing):
| Tier | Combined machine footprint | Working floor area (2-2.5×) | Typical total room, with support space |
|---|---|---|---|
| 100-200 rooms | ~25 m² | ~55-65 m² | ~90-120 m² |
| 300-500 rooms | ~53 m² | ~105-130 m² | ~180-220 m² |
| 600-1,000 rooms | ~72 m² | ~145-180 m² | ~280-350 m²+ |
Actual room requirements vary considerably with layout style (straight-line soiled-to-clean flow vs. U-shaped) and local building constraints. Treat these as a starting conversation with your equipment supplier or plant designer, not a final number for architectural drawings.

FAQ
How much laundry does a 300-room hotel produce per day?
At 85% design occupancy and the industry mid-range estimate of 6.5 kg per occupied room per day, a 300-room hotel generates roughly 1,650 kg of linen daily. Actual figures shift with property class: resort and full-service hotels with heavier bedding and more towel changes run toward the 8 kg/room end of the range, while limited-service properties run lower.
Is it better to buy fewer large machines or more smaller machines?
Fewer large machines cost less to install (fewer utility connections, less floor space) and are usually the right call up to about 500 rooms. Beyond that, running everything on one or two very large machines creates a single point of failure: if one 120 kg washer goes down for maintenance, you lose a large share of daily capacity at once. Larger properties commonly balance this by running more mid-size units across multiple shifts rather than the fewest possible oversized machines.
Do pillowcases need a separate ironing line, or can they go through the main flatwork ironer?
Either works mechanically. Below roughly 300 rooms, most properties run pillowcases through the main ironer without issue. Past that volume, a dedicated 1400mm pillowcase line clears the volume faster and stops pillowcases from occupying width on the main ironer that large flatwork items need. The section above walks through the sizing math.
How much floor space does an in-house hotel laundry room need?
As a rough planning figure, allow roughly 2-2.5 times your combined machine footprint for the working floor area, then add space for sorting, staging, and linen storage on top. For the room-count tiers in this guide, that works out to roughly 90-120 m² total for 100-200 rooms, 180-220 m² for 300-500 rooms, and 280-350 m²+ for 600-1,000 rooms, always confirmed against an actual layout drawing before finalizing room dimensions.
