What to Consider Before Renovating a K–12 Lab in 2026

A K–12 lab renovation can improve safety, support new teaching methods and make better use of limited space. But the decisions that have the greatest impact are often made before construction begins.

Schools need a clear plan for how the room will be used, which systems must be upgraded and what can realistically be completed within the available budget and schedule. Addressing those questions early can prevent expensive changes later.

If your school is planning a science classroom update, start with these seven considerations.

1. Start With the Curriculum, Not the Furniture

Before choosing cabinets, tables or finishes, define what students and teachers need to do in the space. A middle school general science room has different needs than a high school chemistry lab. A room that supports biology, physics and robotics may need even more flexibility.

Ask practical questions:

• Which subjects and grade levels will use the lab?
• How many students must the room accommodate?
• Will teachers demonstrate experiments while students observe?
• Does the curriculum require gas, water, power, ventilation or specialized equipment?
• Could the program or enrollment change during the life of the lab?

These answers shape the layout. They also help the design team separate true requirements from items that are simply nice to have.

2. Evaluate the Existing Room and Building Systems

A renovation is not limited to what students can see. Older labs may have outdated electrical service, plumbing, gas lines, ventilation or flooring. Existing conditions should be documented before the scope and budget are finalized.

An early site evaluation can identify which components may be reused and which must be replaced. Longo’s planning and design process begins with an evaluation of the current space and the school’s specific needs. That information is then translated into a functional laboratory plan.

3. Build Safety Into the Layout

Safety should guide the floor plan from the start. Students and teachers need clear paths through the room, enough space to work and quick access to emergency equipment. Storage should keep chemicals, equipment and daily supplies organized and appropriately separated.

Depending on the activities performed, a lab may require eyewash stations, emergency showers, fume hoods, safety cabinets or other controls. The National Science Teaching Association’s guidance for scienc and STEM instructional spaces is a useful planning reference, but the final design should also be reviewed against applicable local codes and district requirements.

Longo offers educational safety cabinets and equipment as well as fume hoods designed for educational laboratories.

4. Plan for Accessibility From the Beginning

Accessibility is easier and more cost-effective to address during planning than after equipment has been ordered. Review entrances, aisles, work surfaces, sinks, controls and emergency equipment so students and staff can use the room safely and independently.

The 2010 ADA Standards for Accessible Design provide federal accessibility requirements. State and local requirements may also apply, so schools should confirm the project with their architect and code professionals.

5. Decide Where Flexibility Matters Most

Fixed casework can provide durable storage and a permanent utility layout. Mobile tables and modular furniture make it easier to shift between demonstrations, group experiments and project-based learning. Many schools benefit from a mix of both.

Think about what should remain permanent and what may need to move. Longo’s range of educational laboratory products includes casework, lab tables, workstations, specialty storage and worktops that can be combined around the room’s needs. Schools can also explore completed spaces in the educational project gallery.

6. Create a Schedule That Accounts for More Than Installation

A summer installation date does not mean planning can begin when the school year ends. The full schedule may include site evaluation, design, approvals, product selection, procurement, demolition, trade coordination, installation and final inspection. Long-lead items can affect when work is able to start.

Renovation work can also affect indoor air quality in occupied schools. The U.S. Environmental Protection Agency’s school renovation guidance recommends planning for dust, odors and other contaminants before work begins.

Set the target completion date first. Then work backward with the project team and include time for review, revisions and unexpected conditions.

7. Set Priorities Before Finalizing the Budget

A realistic budget should include more than furniture. Utilities, ventilation, demolition, delivery, installation and site repairs can all affect the total project cost. Separate the scope into three groups: required safety and code items, essential teaching needs and optional upgrades.

This makes value engineering more useful. Instead of cutting items at random, the team can protect the lab’s core function while adjusting materials, configurations or project phases. Schools should also ask whether cooperative or contract purchasing can simplify procurement and reduce costs.

Plan the Renovation Around How the Lab Will Be Used

The best K–12 lab renovations do more than replace old furniture. They create a safer, more functional room that supports instruction now and gives the school room to adapt.

Longo Labs supports laboratory projects from early planning through installation. Schedule a meeting to discuss your space, priorities and timeline.

Frequently Asked Questions

How early should a school begin planning a lab renovation?

Schools should begin as early as possible, especially when the project includes custom furniture, utilities, ventilation or a fixed summer construction window. Early planning allows time for evaluation, design, approvals, procurement and trade coordination.

What should be evaluated before renovating a school science lab?

Evaluate the curriculum, class size, existing utilities, ventilation, accessibility, emergency equipment, storage, furniture condition and available schedule. These factors determine the project scope and budget.

Can a K–12 lab combine fixed and mobile furniture?

Yes. Fixed casework can support permanent storage and utilities, while mobile tables and workstations can make the room easier to reconfigure. The right mix depends on the curriculum and how often the layout needs to change.

How can schools control the cost of a lab renovation?

Define must-have requirements early, evaluate existing conditions, compare material and furniture options, use value engineering and review purchasing contracts or cooperatives. A complete scope also reduces the risk of late additions.
