What Size Sharps Bin Do I Need? Guide for Aesthetic, Tattoo & Acupuncture
Guide to sharps bin sizes from 0.2L to 24L for aesthetics, tattoo and acupuncture clinics. Stay compliant and save money with the right container.
If you're running a clinic, tattoo studio, or acupuncture practice, you've probably stood in front of a shelf of sharps bins wondering: which size do I actually need?
It's a common question, and getting it right matters more than you might think. Choose a bin that's too small, and you'll be replacing it constantly – adding to your costs and your workload. Choose one that's too large, and you'll waste space and money on bins that take months to fill.
In this guide, we'll walk you through the different sharps bin sizes available, explain what each colour lid means, and give you practical advice on choosing the right size for your practice – whether you're doing Botox injections, tattooing, or acupuncture.
Why Choosing the Right Size Matters
Sharps bins aren't one‑size‑fits‑all. They range from tiny 0.2L containers (barely bigger than a mug) all the way up to 24L bins that can hold hundreds of used needles.
The right size depends on three main factors:
- How much waste you generate – how many needles, cartridges, or blades do you use each week or month?
- How often you want collections – do you want to replace bins weekly, monthly, or quarterly?
- How much space you have – a 5L bin takes up very little room; a 24L bin needs more floor space.
Get the balance right, and you'll keep your costs down, your storage tidy, and your compliance up to date.
Sharps Bin Sizes: A Complete Breakdown
Here's a quick overview of the most common sharps bin sizes, what they're typically used for, and who they're best suited to.
| Bin Size |
Best For |
Typical Capacity |
Ideal Collection Frequency |
| 0.2L – 1L |
Very low volume – individual practitioners, occasional use |
~30‑80 needles |
Every 6‑12 months |
| 2L |
Small clinics, one‑person practices, acupuncture |
~80‑150 needles |
Every 3‑6 months |
| 5L |
Medium clinics, tattoo studios, small aesthetics practices |
~250‑400 needles |
Monthly or quarterly |
| 7L – 11L |
Busy practices, multi‑practitioner clinics |
~400‑600 needles |
Monthly or fortnightly |
| 24L |
High‑volume clinics, hospitals, large dental surgeries |
~1000+ needles |
Weekly or fortnightly |
Which Size Is Right for Your Practice?
Let's look at some real‑world examples to help you decide.
Aesthetic Clinics (Botox, Fillers, Microneedling)
Typical waste: Syringes, needles, ampoules, and sometimes glass vials. Most aesthetics clinics generate 5‑20 used needles per session.
Recommendation:
- 2L or 5L – for a solo practitioner seeing 5‑10 clients per week
- 7L – for a busier clinic with multiple practitioners
- Most aesthetics clinics find a 5L bin lasts 1‑2 months, making it a convenient size for quarterly collections.
Tattoo Studios
Typical waste: Needle cartridges (which take up more space than fine needles), plus occasional blade waste.
Recommendation:
- 5L – for a single‑artist studio
- 7L or 11L – for a studio with 2‑3 artists
- Tattoo studios generate more bulky waste than acupuncture or aesthetics practices, so a slightly larger bin is often a better fit.
Acupuncture Practices
Typical waste: Fine acupuncture needles (very compact) and occasional lancets.
Recommendation:
- 2L – for a solo practitioner
- 2L or 5L – for a multi‑practitioner clinic
- Because acupuncture needles are thin and small, a 2L bin can hold hundreds of needles and may last 3‑6 months for a part‑time practitioner.
What About Lid Colours?
You've probably noticed that sharps bins come with different coloured lids. This isn't just for aesthetics – it's a crucial part of waste segregation.
| Lid Colour |
Waste Type |
When to Use |
| Orange |
Non‑medicinal infectious sharps |
Acupuncture needles, tattoo needles, lancets |
| Yellow |
Sharps contaminated with medicines (non‑cytotoxic) |
Botox syringes, filler needles, vials |
| Purple |
Sharps contaminated with cytotoxic / cytostatic medicines |
Chemotherapy treatments (rare in most non‑hospital clinics) |
| Blue |
Pharmaceutical waste (not sharps) |
Expired medicines, empty vials (if not sharps) |
Orange is the most common colour for acupuncture, tattoo, and many aesthetics practices, unless you're disposing of needles that have been used with Botox or other medicines – in which case you may need yellow bins. If you're unsure, your waste provider can help you confirm the right colour for your waste stream.
Should You Size Up or Down?
If you're torn between two sizes, here's a simple rule of thumb: if in doubt, go a size up.
A slightly larger bin is more cost‑effective than one that's too small. Why? Because the cost of a collection is usually the same regardless of the bin size (within reason). So if you're paying £85 for a collection, it's better to have a half‑full 5L bin than an overflowing 2L bin that needs collecting twice as often.
However, don't go too big – a 24L bin in a small clinic will take months to fill and may not be collected for a long time, which can be a storage challenge.
Cost‑Saving Tips for Sharps Disposal
Here are a few ways to keep your sharps disposal costs under control:
- Choose the right size first time – get it right, and you'll avoid unnecessary collections.
- Buy your own bins – many providers (including MediWaste) don't charge rental fees, but if you're on a pay‑as‑you‑go plan, you can buy your own bins from Amazon or a medical supplier for around £6‑£15 and avoid any supply costs.
- Wait until bins are reasonably full – there's no need to book a collection for a bin that's only half‑full.
- Consider a Flexi plan – if you're unsure of your volume, a Flexi plan lets you pay for a block of collections and call us when you're ready.
Common Questions About Sharps Bins
Q: Can I use any size bin for all types of sharps?
A: Yes – the size is about volume, not waste type. However, the lid colour (orange, yellow, purple) is about waste type and must match what you're disposing of.
Q: How many needles fit in a 2L sharps bin?
A: It depends on the needle size, but typically around 80‑150 fine acupuncture needles, or 50‑80 larger syringes.
Q: Can I change bin size later if my volume changes?
A: Absolutely. Most providers (including MediWaste) are happy to adjust your bin size as your practice grows or changes.
Q: Is a larger bin always cheaper?
A: Not always – it depends on your collection frequency and whether you're paying per collection or on a contract. For most small practices, a 5L bin offers the best balance.
Q: Do I need to replace my sharps bin even if it's not full?
A: No – you can keep using it until it reaches the fill line. However, sharps bins should be stored securely and not kept for more than about 12 months in most cases.
Final Thoughts
Choosing the right sharps bin size doesn't have to be complicated. Start by thinking about how much waste you generate, how often you want collections, and how much space you have. For most small clinics and practices, a 2L or 5L bin is a great starting point.
If you're unsure, you can always start with a smaller bin and size up later – or talk to your waste provider for advice. At MediWaste, we're happy to help you work out the best setup for your practice.
