A small apartment home gym works best with compact kit chosen by published footprint and noise. The PowerBlock Sport 24 is listed at 10 x 5.5 x 5.5 in per dumbbell, the Bowflex SelectTech 552 at 43 x 21.2 x 22.8 cm, and a WaterRower stands upright in 51 x 57 x 209 cm.
How much space does home gym equipment need?
It needs from the size of one dumbbell to a clear floor strip of about 2.4 square metres for a rower. The table below uses each maker's own figures.
| Item | In use | Stored | Weight |
|---|---|---|---|
| PowerBlock Sport 24 | 10 x 5.5 x 5.5 in per dumbbell (about 25 x 14 x 14 cm) | Same size; a stand is not included | Not stated on the page |
| Bowflex SelectTech 552 | 43 x 21.2 x 22.8 cm per dumbbell | Storage trays listed as included | Settings from 2.3 to 23.9 kg per dumbbell |
| WaterRower Oak | 209 x 57 x 51 cm; maker recommends a 240 x 100 cm training area | 51 x 57 x 209 cm upright, with water left in the tank | 29 kg dry, 46 kg filled |
| JTX Freedom Air | 230 x 55 x 88 cm | Folds, with transport wheels; folded size not listed; boxed size is 125 x 32 x 62 cm | 40 kg |
| Concept2 RowErg | 244 x 61 cm assembled; 274 x 122 cm with clearance for use | Splits into two pieces; storage footprint 63.5 x 83.8 x 137.2 cm | 26 kg with standard legs |
A recommended training area of 240 x 100 cm works out at 2.4 square metres of clear floor for the WaterRower, as arithmetic from the maker's figure. Concept2's clearance figure of 274 x 122 cm is about 3.3 square metres. Whether that fits depends on your room.
What is the most compact home gym equipment for a flat?
On published dimensions, the PowerBlock Sport 24 is the smallest weights option, listed at 10 x 5.5 x 5.5 in per dumbbell. PowerBlock describes it as its most compact adjustable dumbbell, with a 3 to 24 lb range (about 1.4 to 10.9 kg) per dumbbell. Its page lists two selector pins and two 1.5 lb handles as included and shows a stand only as a separate accessory, so you will need a shelf or floor space for it. Bowflex's range is wider, at 2.3 to 23.9 kg, in a larger per-dumbbell footprint. Indicative prices checked in October 2026 are around £205 and around £608. A fixed pair, such as the PROIRON listed at around £90, takes up space for each weight you add. Resistance bands take up far less room than any dumbbell and have no footprint published here; see our resistance bands guide. Our adjustable dumbbells guide and fixed versus adjustable comparison cover this in detail.
Which rowing machine stores in the least space?
On the makers' stored figures, the WaterRower Oak has the smallest footprint, at 51 x 57 cm standing upright, though it is 209 cm tall. The Concept2 page lists 63.5 x 83.8 x 137.2 cm when split into two pieces, and the JTX Freedom Air folds but its page gives no folded measurements and rates its noise as high. Prices are around £999, £990 and £430 respectively. The WaterRower is 46 kg filled and the Concept2 is lighter at 26 kg with standard legs, while the JTX is 40 kg. Delivery matters in a flat too: JTX lists the boxed Freedom Air at 125 x 32 x 62 cm and 46 kg, which is heavy for a delivery to a flat, and says its 28-day money-back guarantee deducts collection costs from the refund, so a return is not free. See the rowing machine guide, and the rowing machine versus exercise bike comparison if a bike might fit better.
What flooring suits a small flat, and what is not published?
Three flooring products are on this site, and none has a published size or noise figure. By indicative price they are the Nicoman 9-pack (around £60), the AIRHOP 12-pack (around £130) and the GCM roll at 10 m x 1.5 m (around £234). By division, that is about £6.67 per mat for the Nicoman and about £10.83 per tile for the AIRHOP. None has a maker page located, so mat size, thickness and any noise-reduction figure are not verified here, and this page makes no claim about how much noise any of them absorbs. The GCM roll is 15 sq m by its stated dimensions, which is more than six times the 2.4 square metres of the WaterRower's recommended training area, so it is likely more than a flat needs. For a dumbbell corner, count the floor you need by the dumbbell sizes above and buy a pack that covers it, rather than the largest option. Compare options in our flooring guide and rubber versus foam guide.
What should I do about noise from a home gym in a flat?
Talk to your neighbours first and find out when they are likely to be at home. GOV.UK advises always trying to solve a noise problem by talking to the neighbour or through mediation before contacting the council. It says a council can act on an activity that harms health or is a nuisance (a "statutory nuisance"), that councils have a duty to investigate any statutory nuisance, and that breaching a noise abatement order for noise from a home carries a maximum fine of £5,000.
Rhythmic machine noise, such as from a rower rated high by its maker, is more of a consideration than quiet equipment like bands. Because no flooring product here has a published noise figure, treat any claim about absorbing sound with caution. Our noise and ventilation guide goes into the layout side.
Which equipment suits which constraint?
This reasoning follows from the published figures, not from any individual's use.
- Floor area is the tightest limit: the dumbbell sizes above are the smallest, and the WaterRower's upright storage is the smallest rower footprint listed.
- Noise is the tightest limit: a rower with a high noise rating is the item to avoid or schedule carefully, and weights placed on a floor you cannot protect are the other concern.
- Budget is the tightest limit: indicative prices run from around £90 for a fixed pair to around £999 for the WaterRower, so the compact route is also the lower-cost one.
- You expect to move: lighter, smaller items are easier to carry; the PowerBlock's maker page gives no weight, so check the listing.
Can a home gym go in a rented flat?
Yes, with free-standing equipment, but check your tenancy agreement before fixing anything to a wall or floor, and ask your landlord when in doubt. Dumbbells and bands need no fixings. Our renters guide covers equipment that avoids fixings.
How can I store it?
Items that fold, split or stand upright reduce what you must hide away. Our storage ideas guide and the beginner's guide show how to combine them.
Who should look elsewhere?
Anyone who needs a rack, a barbell or a long machine should look elsewhere, because a small flat is the wrong place; see the garage gym guide instead. If noise is a serious concern, a gym membership may suit better, as our cost comparison sets out.
