Commercial rowing machines: a specification and buying guide

A rowing machine is one of the few pieces of cardio equipment that recruits most of the body in a single movement, which is why it earns its floor space in almost every commercial facility. The professional market is polarised: air resistance ergometers on one side, water, magnetic and hydraulic machines on the other. This guide compares the technologies, sets out the maintenance profile that decides the real cost, and gives the siting rules that most specifications leave out.

Short answer. Air resistance is the reference for cross training boxes and performance work because resistance rises with effort and the power reading is comparable between machines. Magnetic resistance is the right answer for hotels, workplace gyms and residential buildings, where noise is the binding constraint. Water suits premium studios that want the feel and the sound. Hydraulic arm machines belong in rehabilitation and very constrained spaces only.

Four technologies and what each one costs you

One point worth stating plainly for cross training operators: benchmark times and competition qualifiers are set on air ergometers. Buying a different resistance type for a box means your athletes cannot compare themselves with the published standards, whatever the machine costs.

What our catalogue lists, and what it does not

Our English catalogue currently lists the Ziva Velocity professional magnetic rower at 1,350 EUR excluding VAT. It is the correct specification for hotels, residences, workplace gyms and any site where noise is the constraint, and it is the machine we recommend by default in those settings. Air ergometers for cross training boxes are sourced per project rather than held as a catalogue line, and we will quote them against your written brief. We would rather say that than sell a magnetic machine into a box where it will be the wrong tool within two months.

Maintenance is where the real cost sits

No competing buying guide covers failures, which is odd, because on a rowing machine the wear pattern is predictable and entirely manageable. The figures below are indicative service costs observed on air ergometers in cross training use at 6 to 8 hours a day, not catalogue prices.

Chalk is the single biggest wear factor on rowing machines in a cross training box. It works its way into the chain, the fan cage and the rail, and it accelerates wear on every component. Two measures deal with it: keep rowing machines at least 3 metres from the lifting area, or move the site to liquid chalk. Operators who separate the two zones report a clear drop in service calls on their rowers.

Siting, floor and quantity

Allow a footprint of about 2.5 x 0.6 metres per machine in use, plus 0.6 metres of clear space behind the flywheel so the fan is not starved and the user can dismount. Machines stored on end need 2.5 metres of ceiling height.

Underneath, a 20 mm dense rubber tile is sufficient because a rowing machine imposes a distributed static load rather than an impact. Our 20 mm high density tile at 1000 kg per cubic metre is 26.00 EUR per square metre excluding VAT, and the Cfl-s1 rated version for public buildings is 42.00 EUR per square metre excluding VAT. There is no case for a 40 mm drop zone tile under a rower.

On quantity, plan one machine per 25 to 30 concurrent members in a general club, and one per 4 to 6 athletes in a cross training box running class formats, because rowing appears in a large share of programmed workouts and queueing is what drives complaints.

Frequently asked questions

How noisy is an air rower in practice?

Around 65 to 75 dB at high effort, which is conversational shouting level. In a standalone box that is a non issue. In a hotel, a residential building or a workplace gym sharing a wall with offices, it usually is, and magnetic resistance is the correct answer there.

Does a rowing machine need a use class?

Yes. Specify class S under ISO 20957-1:2024, which covers professional and commercial use, or class I where the site requires professional inclusive use. The standard defines H, S and I, plus accuracy classes A, B and C. There is no semi professional class, whatever a supplier data sheet may say.

Is the calorie reading accurate?

It is an estimate, useful for comparing one session with another on the same machine and not much else. For programming and for testing, use distance, split and power in watts, which are the figures that are comparable between machines of the same technology.

How long should a commercial rowing machine last?

Five to ten years in intensive daily use, depending on technology and on whether the maintenance routine above is actually carried out. Water machines are at the lower end because tank seals age. Our warranties run from 2 to 5 years depending on range.
