Hot Tub Leveling: Feet and Shims
Short answer: Leveling feet are adjustable supports built into a hot tub's base that raise or lower one corner to balance the tub on uneven ground. Shims are thin wedges placed under the base to fill a small gap. A listing may name these words or leave them out. Read what the seller states, ask what is included, and leave the final placement question to a licensed professional.
Leveling feet and shims in plain words
Leveling feet are adjustable supports at the bottom of a hot tub, with one at each corner or at several points along the base. Turning a foot raises or lowers that corner so the tub can sit level on a surface that is not flat.
Shims are thin wedges, often made of a rigid material, that you slide under the base of the tub to fill a small gap between the tub and the ground. A shim is placed under the tub; it is not a permanent part of the tub itself.
These are general descriptions. A listing may use the words 'leveling feet', 'adjustable feet', 'shims', or 'shim kit'. The site reads only what the listing states, so a missing word is left open rather than read as a 'no'.
How the words read on a listing
On a hot tub listing, 'leveling feet' or 'shims' can appear in the title, in a bullet list, or under what is included. When these words appear in the title, they are usually part of a longer list of extras such as a cover, steps, or a base mat.
A title that names only the model and build, such as a brand line with seats and jets, may not mention the base at all. On this site, that detail is simply not stated. It is not treated as a promise that the tub lacks a way to balance.
To compare two listings, check which one names the base detail. The listing that states 'leveling feet' gives you more information about what is in the box. The other one leaves the question open.
Build, shape and the base
The build word in the title changes how you think about the base. An inflatable hot tub is placed on the ground and filled with air, so its base spreads under the whole footprint. An acrylic hot tub has a rigid shell and a framed base, so its feet are the points that contact the surface.
Shape also matters in general terms. A round hot tub has a circular footprint, while a square hot tub has straight sides. On an uneven surface, any shape must be balanced corner to corner, which is what leveling feet and shims address in plain words.
The seat count and the jet count do not tell you about the base. Read the build word and the shape word for the base question, and read the footprint measurement article to see what the listing's own figures say.
Questions to ask before you buy
Before you order, write down the questions that matter for your spot. These questions keep the base detail and the placement question separate from the build, seats and jets.
- Does the listing state leveling feet or shims in the title or among the included items?
- If the detail is missing, what does the box contain? Ask the seller before you order.
- Where do you plan to place the tub, and is that surface flat in plain words?
- What is the distance from the tub to the outlet you plan to use?
- Ask a licensed professional about the ground under the tub before you finalize your choice. The site does not answer structural or ground questions.
- If you rent, ask your landlord or building manager before you buy.
Comparing two listings on this detail
When two listings are otherwise similar, compare the words they state about the base. One may name 'leveling feet' or 'shims' in the title; the other may not. The one that names the detail offers more information to read.
A listing that combines the base detail with other words, such as 'with leveling feet and shims', is a bundle-style title. That title is read as a single stated package, not as a promise about the tub's performance.
A missing word is never read as 'no leveling'. It simply means the seller did not state it. If that detail matters to you, ask before buying.
The site's hot tub reviews compare listings on stated details only, so the base detail appears only when a listing names it.
What the catalogue cannot tell you
This site reads listing details; it does not measure a tub's stability, durability, or set-up time. No build or brand is presented as safer than another on the words alone.
The same rule applies to every build. Whether a title names an inflatable word or an acrylic word, the base detail is read only when it is stated. This keeps the comparison fair across the catalogue.
For safety guidance around water and pools, official public health pages describe how to protect yourself and others. Refer to those pages and to a licensed professional for any question about placement, ground, or power.
Keep your own checklist when you shop: the stated build, the seats, the heater, the plug-and-play words, and the base detail if it is named. That checklist works for a plug and play hot tub and for a 4 person hot tub.
What to check on delivery
When a listing names leveling feet or shims, that detail is part of what the box should contain. Check the box contents against the listing's stated items when it arrives.
- Look for the leveling feet or shim kit if the listing named them.
- Keep the packaging until you have confirmed the stated items are present.
- Check the model label on the tub and compare it with the listing.
- Photograph the base and the included parts on arrival.
- Contact the seller if a stated item is missing.

Questions
Does every hot tub have leveling feet?
No. A listing states what it states. Some titles name leveling feet or shims; others do not. On this site, a missing word is left open, not read as a 'no'.
Are shims included in the box?
Only if the listing says so. The title may list shims as an included item. If it is not stated, ask the seller what the box contains.
Can I place a hot tub on a lawn?
That is a placement question for you and a licensed professional. The site does not answer structural or ground questions. Ask the seller, your landlord if you rent, and a licensed professional before buying.
What if the listing does not mention leveling at all?
Read that as 'not stated' rather than 'not included'. If the base detail matters to you, ask the seller before you buy.
Do leveling words matter more for an inflatable or an acrylic tub?
Both builds need a balanced base in general terms. The build word changes how the base contacts the ground, but the balanced result is the same goal. Compare what each listing states.
